# Life Processes Class 10 Notes CBSE Science Chapter 6 [Free PDF Download] (2022)

The study of living things is referred to as biology. Organisms refer to all living things, which includes both plants and animals. However, seven life processes influence how we determine if something is alive or not. If anything is alive, it will go through the 7 life processes listed below.

### 1. Movement

Animals and plants both have the ability to move around. Plants are rooted and grow at a leisurely pace. Their roots go deeper into the soil, while their stems reach for the sun. Animals, on the other hand, can shift their entire bodies swiftly. They have the ability to migrate in pursuit of food, shelter, or safety.

### 2. Respiration

The process of getting energy from the food we eat is known as respiration. All living things need to breathe in order to develop, replace worn-out parts and move. Respiration occurs in the cell's mitochondria.

### 3. Sensitivity

All living things are sensitive, which means they are aware of changes in their surroundings. Heat, light, sound, touch, and chemicals with taste and smell are all stimuli that animals respond to swiftly. Plants, on the other hand, appear to be less sensitive and respond more slowly.

### 4. Growth

Growing is a process that occurs in all living creatures. Plants keep growing for the rest of their lives. When animals reach adulthood, they stop growing. Even when development ceases, an animal's body continues to be replenished with materials obtained from its food.

### 5. Excretion

All living things produce waste products, which can be either useless or hazardous to them and hence must be disposed of. The process of excretion is the removal of metabolic waste. Plants retain waste substances in their leaves, and as the leaves fall off, the garbage is eliminated. Other waste substances exit the body in urine and sweat, and animals breathe out waste carbon dioxide.

Note: Egestion, not excretion, is the process of getting rid of faeces or undigested food.

### 6. Reproduction

In order for their species to survive, all living organisms must produce offspring who are genetically identical to themselves. Reproduction is the term for this process. Plants generate seeds, which germinate and produce new plants of the same species. Animals either lay eggs or have children. There are two types of reproduction: sexual and asexual. Sexual reproduction includes two parents and the union of two gametes, whereas asexual reproduction involves one parent reproducing itself.

### 7. Nutrition

Food is required for energy and growth in both plants and animals. Photosynthesis allows plants to produce their own food. Simple molecules like carbon dioxide and water are converted into more complex carbohydrate molecules using sunlight. Animals are unable to produce their own food and must rely on the nourishment of other plants and animals. Animals consume complicated substances and deconstruct them into small, soluble molecules that can be utilised for energy and growth.

• Nutrition: The process of nutrition provides the energy required to carry out various living activities. Organisms are classed as autotrophs or heterotrophs based on their mode of nourishment.

### A. Autotrophic Nutrition:

When organisms obtain their organic components from inorganic sources, they are said to be autotrophic. Carbon dioxide and nitrates are the primary sources of carbon and nitrogen, respectively. All green plants are autotrophic, meaning they use light as a source of energy to produce food via photosynthesis.

$6C{{O}_{2}}+12{{H}_{2}}O\xrightarrow[\text{Chlorophyll}]{\text{Sunlight}}{{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{H}_{2}}O+6{{O}_{2}}$

During this process, the following things happen.

1. Light energy absorption by chlorophyll.

2. Light energy is converted to chemical energy, and water molecules are divided into hydrogen and oxygen.

3. Carbon dioxide is converted to carbohydrates.

The roots of these green plants collect water from the soil. Sunlight enters the plant through its stomata and is absorbed by chlorophyll and other green elements of the plant.

The roots of these green plants collect water from the soil. Sunlight enters the plant through its stomata and is absorbed by chlorophyll and other green elements of the plant.

### B. Heterotrophic Nutrition: Heterotrophs are entirely reliant on autotrophs for their food.

Heterotrophic nutrition is divided into three categories:

1. Holozoic Nutrition: Complex foods are ingested through a specialised digestive system and broken down into little pieces so that they can be absorbed. For example, Amoeba and Humans.

2. Saprophytic Nutrition: It refers to the feeding of organisms on the dead organic remnants of other creatures. Fungi, for example, enjoy bread moulds, yeast, and mushrooms.

3. Parasitic Nutrition: Parasites feed on other living beings (the host), with no benefit to the host. Cuscuta, ticks, lice, leeches, and tapeworms are examples.

### How Do Organisms Obtain their Nutrition?

Food can be taken in by the entire surface of single-celled organisms. For example, an amoeba takes in food by building a food-vacuole out of transient finger-like extensions of the cell surface that fuse over the food particle. Complex compounds are broken down inside the food vacuole into simpler ones, which eventually diffuse into the cytoplasm. The remaining undigested material is pushed to the cell's surface and discarded.

• Human Nutrition: Food digestion takes place in the alimentary canal, which is made up of several organs and glands.

• The remaining undigested material is moved to the surface of the cell and thrown out.

• Food is chewed into minute particles in the mouth and combined with saliva, which contains amylase for starch digestion.

• Food goes through the pharynx and oesophagus on its way to the stomach when swallowed. Pepsin (a protein-digesting enzyme), $HCl$ and mucus are found in gastric juice.

• The hydrochloric acid generates an acidic environment for the enzyme pepsin to work in. Under normal circumstances, mucus protects the stomach's inner lining from the acid's activity.

• The meal now enters the small intestine from the stomach. The small intestine is where carbs, proteins, and lipids are completely digested.

• Bile is secreted by the liver, which emulsifies fat.

• Pancreatic juice, which contains the enzymes amylase, trypsin, and lipase for digesting starch, proteins, and fats, is secreted by the pancreas.

• Carbohydrates, proteins, and fats are entirely digested in the small intestine, resulting in glucose, amino acids, fatty acids, and glycerol.

• The small intestine villi absorb the digested food and deliver it to all of the body's cells.

• The undigested food is transferred to the large intestine, where it is absorbed by additional villi. The anus is used to eliminate the rest of the material from the body.

### Nutrition in Paramoecium

• Paramoecium attains nutrition through the process of holozoic nutrition, where the organism ingests liquid or solid food particles inside its body.

• The cilia present on the Paramoecium help them to engulf the food particles through the oral groove.

• The digested food passes through the cytoplasm by the process of cyclosis and reaches the food vacuoles, which is then absorbed by the cytoplasm.

• The undigested food is later, taken out through the tiny pore known as cytopyge or anal pore.

### Respiration:

The digested food items are broken down during breathing to release energy in the form of ATP.

Respiration can be one of two forms, depending on the amount of oxygen required:

1. Aerobic respiration: This occurs when there is air present (oxygen).

2. Anaerobic respiration: This occurs when there is no (air) oxygen present.

• The breakdown of glucose, a six-carbon molecule, into pyruvate, a three-carbon molecule, is the first step in all cases. The cytoplasm was involved in this process. Pyruvate can also be converted to ethanol and carbon dioxide. During fermentation, yeast undergoes this process. Anaerobic respiration is the name given to a process that occurs without the presence of oxygen (air). In the mitochondria, pyruvate is broken down utilising oxygen.

• When compared to anaerobic respiration, aerobic respiration releases a lot of energy.

• When there is a shortage of oxygen in our muscle cells, pyruvate is transformed into lactic acid. Cramping occurs when lactic acid builds up in our muscles as a result of an abrupt activity.

Aquatic species use oxygen dissolved in water for respiration, whereas terrestrial organisms use air oxygen.

In humans, inhalation of air occurs through the following pathway: Nostrils $\to$Nasal passage $\to$ Pharynx $\to$ Larynx $\to$ Trachea $\to$ Bronchus $\to$ Bronchiole $\to$ Alveolus

• Air enters the body via the nostrils in humans. Fine hairs line the channel, filtering the air that passes through the nose. Mucus lines the channel, assisting in the process. The air then enters the lungs via the throat. The neck is lined with cartilage rings. They keep the airway from collapsing.

• The channel within the lungs divides into smaller and smaller tubes that eventually finish in balloon-line formations known as alveoli.

• The alveoli of the lungs are densely packed with blood and serve as locations for gas exchange $\left( {{O}_{2}}\text{ and }C{{O}_{2}} \right)$ between the blood and the atmosphere.

• The blood transports carbon dioxide from the rest of the body to the alveoli, while blood in the alveolar blood vessels absorbs oxygen from the alveolar air and transports it to all of the body's cells. During the breathing cycle, when air is inhaled and exhaled, the lungs always have a residual volume of air so that oxygen may be absorbed and carbon dioxide can be exhaled in adequate time.

• The respiratory pigment haemoglobin transports oxygen from the lungs to the body's various tissues in humans. The red blood cells contain this pigment.

### Transportation:

• Transportation in Human Beings:

The heart, blood, and blood arteries make up the circulatory system, which transports various materials throughout the body.

The Heart:

• The human heart is divided into four chambers: two atria (right and left) and two ventricles (right and left) (right and left). These chambers prevent oxygen-rich blood from mixing with carbon dioxide-rich blood. Deoxygenated blood is delivered to the right half of the heart, while oxygenated blood is delivered to the left.

• The carbon dioxide-rich blood must reach the lungs in order for the carbon dioxide to be eliminated, and the oxygenated blood must return to the heart. The oxygen-rich blood is subsequently circulated throughout the body.

• The walls of the ventricles are significantly thicker than the walls of the atrium.

• Humans have twofold circulation, which means blood passes through the heart twice and oxygenated and deoxygenated blood are separated completely.

• Arteries transport blood from the heart to various regions of the body, while veins return it to the heart. Thin capillaries connect arteries to veins, allowing materials to be exchanged between the blood and cells.

• Platelet cells are found in blood and circulate throughout the body, preventing blood loss at the site of damage.

• Lymph has a role in transportation as well. It's similar to blood plasma, but it's colourless and has less protein. From the intercellular gaps, it empties into lymphatic capillaries, which connect to major lymph arteries, which then open into bigger veins. It transports fat from the intestine that has been digested and absorbed, as well as excess fluid from extracellular space back into the circulation.

### Transportation in plants:

• Plant transport systems will carry raw materials from roots and energy stores from leaves. These two paths are made up of conducting tubes that are set up separately. The xylem, for example, transports water and minerals from the soil. The phloem, on the other hand, carries photosynthetic products from the leaves to other sections of the plant.

• The xylem tissue of roots stems, and leaves (tracheids and vessels) are interwoven to form a continuous system of water transmitting channels that reaches all parts of the plant. Water is driven into the xylem cells of the roots as a result of suction pressure created by transpiration. Then, through the interconnecting water-carrying channels, water moves steadily from the root xylem to all sections of the plant.

• Transpiration is the loss of water from the plant's aerial portions in the form of vapour. As a result, it aids in the absorption and upward transfer of dissolved minerals in water from the roots to the leaves. It also controls the temperature.

• Translocation happens in phloem and is the movement of soluble photosynthetic products. Amino acids and other chemicals are transported via it. Food and other substances are transported in the sieve tubes in both upward and downward directions with the help of nearby partner cells.

• Energy is used to facilitate translocation in the phloem. Sucrose is transported into phloem tissue with the help of ATP energy. This causes the tissue's osmotic pressure to rise, allowing water to enter. This is the pressure. This allows the phloem to transfer material in accordance with the needs of the plant. For example, in the spring, sugar stored in root or stem tissue would be transported to the buds which need energy to grow.

### Excretion:

The toxic metabolic nitrogenous wastes produced are excreted from the body during excretion.

Excretion in Human Beings:

• The excretory system in humans consists of two kidneys, two ureters, the urine bladder, and the urethra. The abdomen has two kidneys, one on each side of the backbone. The ureters transport urine from the kidneys to the urinary bladder, where it is held until it is discharged through the urethra.

• Nephrons are basic filtration units found in great numbers in each kidney. As the urine passes along the tube, several substances in the initial filtrate, such as glucose, amino acids, salts, and a significant amount of water, are selectively reabsorbed. The amount of water reabsorbed is determined by the amount of excess water in the body as well as the amount of dissolved waste to be expelled. The urine produced by each kidney eventually enters the ureter, a lengthy tube that connects the kidneys to the urinary bladder until the inflated bladder causes the urge to send it out through the urethra. Because the bladder is muscular, it is controlled by the neurological system. As a result, we are able to manage our urge to urinate.

Excretion in plants:

• Plants do not have an excretory system and excrete through a variety of mechanisms, including transpiration, waste release into the surrounding soil, leaf loss, and waste storage in cell vacuoles. Other waste materials are retained in ancient xylem as resins and gums.

### Why is the Class 10th Board Examination Important For You?

In 2010, the CBSE had made Class 10 board options to help remove the fear of exams from students since it was causing stress in students. At that time, students were evaluated on the basis of CCE or Continuous and Comprehensive Evaluation. But, after 2016, there were concerns over the removal of board examinations and the impact it was having on the student’s future. Thus, in 2018, it was decided to make Class 10 board exams compulsory again. It shows why the importance of board examinations cannot be ignored. Here are some of the top reasons why Class 10 board examination is necessary for students –

• Learn How to Handle Stress – The reason why Class 10 was made optional was to avoid stress in students. But, another way to look at it is to change how students perceived stress. It is essential that students take Class 10 board examinations as an experience where they know how to tackle stress and learn new skills such as planning, scheduling, time management, and more. Instead of focusing on the negative impact of the fear of exams, you should focus more on the positive aspects of the exam and learn how to handle it. When you train your brain to focus on only the positive things, it will enhance your productivity and also make you more capable.

• Help You Understand Where You Stand – For most students, their Class 10 board examination will be the first national exam that they appear in. It means that they will not just be competing with their classmates, but also with students across India. Competitions are facts of life, and there is no way for students to escape it. Since CBSE board examination is conduction on a national level, you can know where you stand in the competition. If you do well, then you are among the top students, but if you do not do well, it means you need to put in more effort than before. You will feel happy when you score well in the exams.

• Know How Class 10 Board Exams will be Like – Class 12 board exam is an important exam as it will allow you to choose your career path thereon. Class 10 board exams provide you an opportunity to know what Class 10 holds for you. You will experience going to another school, be around teachers you do not know. It will make you more confident about your capability and help you face the class 10 boards without any worries.

• Learn How to Face Your Fear – When you have successfully faced and sat for the Class 10 board exams, you will be able to face any kind of test thereon. You will become confident in facing much tougher exams. Instead of seeing exams as a hurdle or running away from tough questions, you will be able to take exams without the fear of failing it.

• Allow You to Learn – Even though students do not like the pressure of exams, taking the Class 10 board exams will help you learn how to deal with pressure and go through tough situations. You will learn how to multitask, perform under pressure, and also manage your time well. So, giving Class 10 board exams will allow you to learn new skills and also work towards finding solutions to problems.

• Helps If You Want to Change School – If you have been looking to change schools, getting good marks in Class 10 will surely make it easier for you. Most schools will want students with excellent marks in their Class 10 examinations. Also, if your parents are in a transferable job, it will become easy for you to get admission in class 11 in a reputed class wherever you go.

• Allow You to Judge Yourself – You will be able to judge your performance in Class 10 board exams on a national level. Since your school has a lower number of students, it is not always easy to know where you stand in the competitive world out there. Thus, giving Class 10 board exams allows you to know where you actually stand and make you more confident about your abilities. It also tells you where you need to work hard.

• Achieve Your First Milestone – Even though class 12 board exams are important for your further studies and career, Class 10 board exams allow you to know what to expect in Class 10. When you score high marks, you will see it as a first milestone, and it will push you to perform better.

• Helps You Get Out of Shell – When you start to compare your results with that of students in the country, you will be able to come out of the comfort zone. You will be able to judge yourself and assess how you are doing in comparison to other students. The sooner you are able to get out of the comfort zone, the better it will be for you.

• Helps You Become More Adaptable – Appearing for Class 10 exams allow you to become more adaptable to exams. You learn how it feels, and it becomes a part of your life. You will feel less stressed when you are put in different situations, such as other competitive exams, when you grow a little older.

So, when you start to sit for your Class 10 exams, instead of fearing it, keep the above points in mind so that you can give the exam your best and perform exceptionally well. Our Class 10 Science Notes life processes are here to help you achieve success and coming out of the examination triumphant.

### What is the Expected Weightage of Questions from the Class 10 Science Chapter 6 – Life Processes?

The Class 10 Science Chapter 6 life process Notes are important for you because you can expect to get questions carrying anywhere from 12-15 marks in your board examinations. If you consider the previous year’s question papers of Class 10 board exams, almost 5-7 questions were asked from this Chapter, including practical-based questions from this particular Chapter. So, it is not wrong to say that you can expect a minimum of 2 questions from the Chapter that carry 1, 2, 3, or 5 marks. Even the diagrams from the Chapter are important as they have been asked in the previous examinations. Thus, there is no reason for you to skip any section of this Chapter as even the smallest of details from the NCERT book is important. Make sure that you cover all of it using our life processes Class 10 NCERT book PDF so that you stand to score full marks in your Science Class 10 board exams.

### Importance of Before an Examination

If you have studied hard and then failed to get results, it might be because you did not revise the texts properly. No matter how hard you study, in the end, the will play an important part in how much you score. Often students have a problem in recalling what they have studied during the exam. The inability to recollect what you have learned will only increase your anxiety and stress. It will make you nervous, and you will write the wrong answers even if you know the right ones.

The chances are that you might get busy in your daily routine that you do not revise the Chapters in periodic intervals. No matter how hard you work, without, everything else will be a waste. Thus, before the exam, it is essential that you revise your Chapters. Rather than adding new information to your brain before the exam, it is crucial that stick to what you have learned before. Keep on revising what you have already learned so that you remember them for long.

Problems with revising using the NCERT book are that it is boring. Reading the same text, again and again, will not make you think. Once you start to get bored, the from the NCERT book will become ineffective, and your morale will take a dip. Thus, using our Class 10 Science Notes life processes will make your more effective.

Several glands produce digestive juices that help in digestion of the food.. Mechanical digestion of food takes place in the buccal cavity where teeth masticate the food, saliva gets mixed and it turns into a bolus.. Chyme enters into the small intestine where complete digestion takes place due to the action of various enzymes present in the pancreatic juice, bile and intestinal juice.. Glands present in the wall of the stomach and small intestine also contribute to the digestion of food.. Many small glands present in the inner layer of the stomach and intestine take part in the digestion of food.. The glands present in the epithelial lining of the small intestine and large intestine are called intestinal glands.. Pancreatic juice coming from the pancreas, bile from the liver and intestinal juice secreted by the intestinal glands complete the digestion of food material.. The pressure exerted by the blood when it flows through the blood vessels is called blood pressure.. Transport of food in the plant through phloem via a process such as mass flow is called as translocation.

(2013). Answer:. (a) Arteries have thick walls because these vessels carry blood from the heart to all the parts of the body and blood emerges from the heart under high pressure.. In a fish, the heart pumps deoxygenated blood to gills where oxygenation of blood takes place.. (2012). Answer:. (a) The chamber of the heart that pumps out deoxygenated blood – Right ventricle. (b) The blood vessel that carries away oxygenated blood from the heart – Aorta. (c) The blood vessel that receives deoxygenated blood from the lower part of our body – Inferior Vena Cava. (2012). Answer:. (a) (i) Largest gland – Liver. (ii) Gland that secretes digestive enzymes and hormone – Pancreas. (iii) Part where HCl is produced – Stomach. (iv) Part where digested food is absorbed – Small intestine. The presence of villi gives the inner walls of the small intestine a very large surface area and the large surface area of small intestine helps in the rapid absorption of digested food.. In a four chambered heart, the left side and right side of the heart are completely separated to prevent the oxygenated blood from mixing with deoxygenated blood.. Answer:. (a) Double circulation of blood means, that the blood enters twice in the heart during its one circulation in other parts of the body.. Double circulation of blood is necessary to separate the oxygenated blood from the de-oxygenated blood to provide more energy for efficient working of body organs.
