Download NCERT Solutions for all classes. Students of the upper primary level (Class 6, 7 and 8) are already well informed and are keen to find and learn more. According to CBSE, while assigning and preparing homework for the students, it is important to note they are able to develop the skills like relating, thinking, concluding, inferring. Homework should be such that the student neither feel it burdensome nor they lose interest in the subject matter. Moreover it is useful in providing them a happy experience. Homework therefore needs to be thought about and worked upon differently. Emphasis should be given on Vedic mathematics, designing quality homework rather than its quantity. Download NCERT Books and apps based on latest CBSE Syllabus.

Encompassing the aforesaid ideas, the CBSE has brought forth a Manual, “Alternatives to Holiday Homework” for classes VI to VIII. It is collection of ideas transformed into suggestive activities that are creative, interesting, meaningful and interactive, enhancing various skills, directly or indirectly related to subject matter providing students to enhance their learning and gaining knowledge based on NCERT Books following the latest CBSE Syllabus.

A well rounded development of individual knowledge happens not only from textbooks and formal education but more from the learner’s personal experiences, individual inquisitive nature and social surroundings. Homework is an area of importance and to make it more relevant for the NCERT Books classes 6th, 7th and 8th, appropriate strategies and meaningful activities may be suggested to the schools that give more time to child to explore the environment to develop creative thinking.

These activities (like OTBA for class 9 & 11 ) would be so framed that they keep the child interested in subjects and therefore would also help in enhancing the learning power. Homework is one of the areas that need urgent attention. As the students of class VI, VII and VIII develop a certain learning style and want to know and find more and more. Efforts should be made to make homework more creative and interesting so that the students do not feel burdensome while doing the same and the ultimate purpose of providing homework is served.

A survey was conducted through questionnaire prepared by CBSE to collect feedback from parents, teachers, students and other educationists on “Alternatives to Homework at Upper Primary Level” for Class Sixth, Seventh and Eighth so that appropriate strategies and meaningful activities can be designed and suggested to schools. The questions were directed to know the ideal quantity and purpose of the homework, whether homework should be assigned in all the subjects, internet usage should be a part of the homework or not, how homework helps in teaching.

Keeping in view emerging issues, there is a need to think about giving quality homework emphasizing on acquiring applied learning skills. Few points can be kept in mind while designing a quality homework by teachers: 1, Provide students capacity building activities which are followed up and acknowledged like drawing, creative writing, making puzzles, stories, plays, online games, reading online books and craft.

2. Provide them assignment sheets which improve their reading & writing abilities. Homework must enable the student to practice a skill independently. 3. A possible discussion can be held with different children on what they would like to do at home to improve in which ever area they deem necessary. Homework must be designed in a way that maximizes the chances of its completion by the students.

4. Parents should be able to understand the child’s needs and schools suggestions on how to learn mathematics, logical reasoning, etc. by doing puzzles, writing letters, reading to elders from the newspapers, making household lists, recipe making and cooking. 5. Learners who have dyslexia or number difficulty should have practice assignments overcoming their problems.

The child in middle school have a keenness to discover more and prepare for the examination. Learning is about developing new faculties, which become useful as an adult. The years 12 to 15 are years when rules become important, and doing well, excelling are given importance both at home and in the class. As the child grows chronically his/her emotional maturity also grows and there are interests which are beyond just what lessons can give.

The homework assigned should: 1. enhance study habits and practice skills (which learners are able to perform independently) 2. reinforce necessary skills both scholastic and co-scholastic among the learners. 3. enable learners to become independent learners and thinkers and develop among them 21st century skills so that they can participate in Make in India in future. 4. lead to the improvement in the academic achievement of the learner.

5. expand on the existing knowledge of the learners and be a part of the already acquired competencies in the classroom. 6. not put unneeded pressure or stress by including new learning material or difficult material to be worked upon by learners themselves. 7. be CBSE Syllabus based and as per developmental needs of the learners. 8. not require specific resources or technology which is not accessible to all learners. 9. have clearly defined, purposeful, creative and engaging activities.

It is also advised that teachers can refer to Life Skills Manuals, Health Manuals and Environmental Education Manuals which contain age appropriate and interesting activities which can be taken up by the learners individually. These activities can be assigned to learners so as to enhance their life skills, values and make them health conscious.

Homework is needed, and necessary for a teacher to be able to follow up with each child. The correction and feedback on homework is an important input that helps both parents and children to follow up and improve in areas which are needed. The recourse extra classes, can be reduced if the homework is used for learning improvement and acquisition of diverse skills. We are providing a handful help to solve or helping in solving the holiday homework.

What are concepts of the Holiday Homework for Class 1, 2, 3, 4 and 5?

Class 9 Science Chapter 5 Textbook Questions and Answers

INTEXT QUESTIONS

Question 1: Who discovered cells and how?

Answer: Cells were discovered in 1665 by an English Botanist, Robert Hooke. He used a primitive microscope to observe cells in a cork slice.

Question 2: Why is the cell called the structural and functional unit of life?

Answer: A cell is capable of carrying out all the life functions; such as nutrition, excretion, respiration, etc. Hence a cell is called the functional unit of life. Additionally, the cell is the smallest unit of life and all the living beings are made up of cells. Hence a cell is called the structural unit of life.

PAGE NO. 61

Question 1: How do substances like CO 2 and water move in and out of the cell? Discuss.

Answer: Substances move in and out of the cell because of diffusion. Diffusion is the random movement of particles in order to attain concentration equilibrium. The movement of water through a semi-permeable membrane is called osmosis. It is important to note that plasma membrane is a semi-permeable membrane. Water always moves from high water concentration to low water concentration.

CO 2 moves by diffusion – These cellular waste accumulates in high concentrations in the cell, whereas the concentration of CO 2 in the external surroundings is comparatively lower. This difference in the concentration level inside and out of the cell causes the CO 2 to diffuse from a region of higher(within the cell) to a lower concentration.

H 2 O diffuses by osmosis through the cell membrane. It moves from a region of higher concentration to a lower concentrated region through a selectively permeable membrane until equilibrium is reached.

Question 2: Why is the plasma membrane called a selectively permeable membrane?

Answer: Plasma membrane allows passage to some selected substances. Hence it is called a selectively permeable or semi-permeable membrane.

The cell membrane or the plasma membrane is known as a selectively permeable membrane because it regulates the movement of substances in and out of the cell. This means that the plasma membrane allows the entry of only some substances and prevents the movement of some other materials.

Question 1: Fill in the gaps in the following table illustrating differences between prokaryotic and eukaryotic cells.

Question 1: Can you name the two organelles we have studied that contain their own genetic material?

Answer: Mitochondria and plastids are the two organelles that contain their own genetic material. Both these organelles have their own DNA and ribosomes.

Question 2: If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen?

Answer: Cell is the smallest unit of life, which is capable of all living functions. If the organisation of a cell is destroyed due to some physical or chemical influence, then the ability of the cell to perform all living functions such as respiration, nutrition, excretion, etc. would be affected.

Question 3: Why are lysosomes known as suicide bags?

Answer: The lysosomes contain very powerful hydrolytic enzymes which are capable of breaking down organic matter. For example, when a cell gets damaged, then lysosomes burst and enzymes digest their own cell. Hence, the lysosomes are known as ‘suicide bags’ of cells

Question 4: Where are proteins synthesized inside the cell?

Answer: Ribosomes are the site for protein synthesis. Ribosomes are very small structures found either in a free state, suspended in the cytoplasm, or attached to the surface of the endoplasmic reticulum. They are composed of ribonucleic acids and proteins.

Question 1: Make a comparison to write down ways in which plant cells are different from animal cells.

Answer: The cells of animals and plants have the following differences:

Question 2: How is a prokaryotic cell different from a eukaryotic cell?

Answer: Difference between prokaryotic cell and eukaryotic cell:

Question 3: What would happen if the plasma membrane ruptures or breaks down?

Answer: Plasma membrane provides a container for the cell organelles and cytoplasm. Moreover, plasma membrane also protects the contents of a cell from external environment. In case the plasma membrane ruptures or breaks down, the cell contents would be exposed to the external environment. This would prove lethal for the cell and the cell would cease to exist.

Question 4: What would happen to the life of a cell if there is no Golgi apparatus?

Answer: Golgi apparatus plays the important role of packaging various substances for further use or for storage. If there was no Golgi apparatus, various substances would not be in a position to be transformed in proper forms for further use. Certain substances; like protein and lipid are important for the formation of plasma membrane and hence absence of Golgi apparatus will hamper the formation of new cells during cell division.

Question 5: Which organelle is known as the powerhouse of the cell? Why?

Answer: Mitochondria are known as the powerhouse of cells. Mitochondria create energy for the cell, and this process of creating energy for the cell is known as cellular respiration. Most chemical reactions involved in cellular respiration occur in the mitochondria. The energy required for various chemical activities needed for life is released by the mitochondria in the form of ATP (Adenosine triphosphate) molecules. For this reason, mitochondria are known as the powerhouse of cells

Question 6: Where do the lipids and proteins constituting the cell membrane get synthesised?

Answer: Lipids are synthesized in the endoplasmic reticulum. Protein is synthesized in ribosomes which are usually present on the rough ER.

Question 7: How does Amoeba obtain its food?

Answer: Amoeba obtains its food through a process called phagocytosis. The cell membrane of amoeba is projected into numerous finger-like outgrowths; called pseudopodia. Amoeba surrounds a food particle by pseudopodia and makes a food vacuole; after engulfing the food.

Question 8: What is osmosis?

Answer: The process of movement of a water molecule from a region of higher concentration to a region of lower concentration through a semipermeable membrane is known as osmosis.

Question 9: Carry out the following osmosis experiment:

Take four peeled potato halves and scoop each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,

(a) Keep cup A empty (b) Put one teaspoon sugar in cup B (c) Put one teaspoon salt in cup C (d) Put one teaspoon sugar in the boiled potato cup D.

Keep these for two hours. Then observe the four potato cups and answer the following:

(i) Explain why water gathers in the hollowed portion of B and C. (ii) Why is potato A necessary for this experiment? (iii) Explain why water does not gather in the hollowed out portions of A and D.

NCERT Solutions for Class 9 Science Chapter 5 The Fundamental Unit of Life part 1

Experimental set up

(i) Water gathers in the hollowed portions of set-up B and C because water enters the potato as a result of osmosis. Since the medium surrounding the cell has a higher water concentration than the cell, the water moves inside by osmosis. Hence, water gathers in the hollowed portions of the potato cup.

(ii) Potato A in the experiment acts as a control set-up. No water gathers in the hollowed portions of potato A.

(iii) Water does not gather in the hollowed portions of potato A because potato cup A is empty. It is a control set-up in the experiment.

Water is not able to enter potato D because the potato used here is boiled. Boiling denatures the proteins present in the cell membrane and thus, disrupts the cell membrane. For osmosis, a semi-permeable membrane is required, which is disrupted in this case. Therefore, osmosis will not occur. Hence, water does not enter the boiled potato cup.

Question 10: Which type of cell division is required for growth and repair of body and which type is involved in formation of gametes?

Answer: There are two ways in which a cell divides:

Mitosis is the type of cell division that is involved in the growth and repair of body whereas meiosis is a type of cell division which results in the formation of gametes.

Exercise-5.1 page: 59.

1. Who discovered cells, and how?

In 1665, Robert Hooke discovered cells while examining a thin slice of cork through a self-designed microscope. He observed that the cork resembled the structure of a honeycomb consisting of numerous tiny compartments. The minuscule boxes are referred to as cells.

2. Why is the cell called the structural and functional unit of life?

Cells form the structure of an entity. A group of cells form a tissue, further an organ and ultimately an organ system. They perform fundamental functions and life processes such as respiration, digestion, excretion etc., in both unicellular and multicellular entities. They perform all the activities independently. Hence, cells are referred to as structural and fundamental units of life.

Exercise-5.2.1 Page: 61

3. How do substances like CO 2 and water move in and out of the cell? Discuss.

CO 2 moves by diffusion. The cellular waste accumulates in high concentrations in the cell, whereas the concentration of CO 2 in the external surroundings is comparatively lower. This difference in the concentration level inside and outside of the cell causes the CO 2 to diffuse from a region of higher (within the cell) to a lower concentration.

4. Why is the plasma membrane called a selectively permeable membrane?

The plasma membrane is called as a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. Not all molecules are free to diffuse.

Exercise-5.2.2-5.2.4 Page: 63

5. Fill in the gaps in the following table, illustrating the differences between prokaryotic and eukaryotic cells.

The two organelles which have their own genetic material are

1. Mitochondria

2. Plastids

7. If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen?

In the event of any damage to cells and when the revival of cells is not possible, Lysosomes burst, and enzymes digest such cells. This is why lysosomes are often referred to as ‘suicide bags’.

8. Why are lysosomes known as suicide bags?

When there is damage to the cell and when revival is not possible, lysosomes may burst, and the enzymes digest their own cell. Consequently, lysosomes are known as suicide bags.

9. Where are proteins synthesised inside the cell?

Protein synthesis in cells takes place in ribosomes. Hence, ribosomes are also referred to as protein factories. Ribosomes are particles that are found attached to the rough endoplasmic reticulum.

1. Make a comparison and write down ways in which plant cells are different from animal cells.

The following table depicts the differences between plant cells and animal cells.

2. How is a prokaryotic cell different from a eukaryotic cell?

The following are the differences between prokaryotic and eukaryotic cells.

3. What would happen if the plasma membrane ruptures or breaks down?

If the plasma membrane ruptures or breaks down, then molecules of some substances will freely move in and out of the cells. As the plasma membrane acts as a mechanical barrier, the exchange of material from its surroundings through osmosis or diffusion in a cell won’t take place. Consequently, the cell would die due to the disappearance of the protoplasmic material.

4. What would happen to the life of a cell if there was no Golgi apparatus?

The Golgi apparatus consists of stacks of membrane-bound vesicles whose functions are as follows:

Storage of substances
Packaging of substances
Manufacture of substances

Without the Golgi apparatus, the cells will be disabled from packing and dispatching materials that were produced by the cells. The Golgi apparatus is also involved in the formation of cells. Hence, in the absence of the Golgi apparatus, cells will not be produced.

5. Which organelle is known as the powerhouse of the cell? Why?

Mitochondria are known as the powerhouse of the cell. It is because it releases the energy required for different activities of life. Mitochondria releases energy in the form of ATP (Adenosine triphosphate) molecules, essential for numerous chemical activities of life. Hence, ATP is often referred to as the ‘energy currency of the cell’.

6. Where do the lipids and proteins constituting the cell membrane get synthesised?

Lipids and proteins are synthesised in the ER (Endoplasmic Reticulum).

How does an Amoeba obtain its food?

Through the process of endocytosis, an Amoeba obtains its food. As its cell membrane is flexible enough, food particles are engulfed, forming a food vacuole girdling it, which is assisted by the pseudopodia. Amoeba secretes digestive enzymes to bring about digestion of the engulfed particle once the food is trapped.

What is osmosis?

The process of movement of a water molecule from a region of higher concentration to a region of lower concentration through a semipermeable membrane is known as osmosis.

9. Carry out the following osmosis experiment:

Take four peeled potato halves and scoop each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,

(a) Keep cup A empty

(b) Put one teaspoon sugar in cup B

(d) Put one teaspoon sugar in the boiled potato cup D.

Keep these for two hours. Then observe the four potato cups and answer the following:

(i) Explain why water gathers in the hollowed portion of B and C.

(ii) Why is potato A necessary for this experiment?

(iii) Explain why water does not gather in the hollowed-out portions of A and D.

(i) Water accumulates in the hollowed portions of B and C as a difference in the water concentration

is observed. Thereby, endosmosis occurs as the cells act as a semipermeable membrane.

(ii) Potato A is essential in this experiment as it is significant to compare different scenarios seen in

potato cups B, C and D. Potato A in this experiment clearly shows that the potato cavity on its

own cannot bring about water movement.

(iii) Cup in A does not show any change in the water flow concentration for osmosis to occur, which

requires concentration to be higher than the other. Cells in cup D are dead; thus, there is no

existence of a semipermeable membrane for water flow. Consequently, osmosis does not occur.

10. Which type of cell division is required for the growth and repair of the body, and which type is involved in the formation of gametes?

There are two ways in which a cell divides:

Mitosis is the type of cell division that is involved in the growth and repair of the body, whereas meiosis is a type of cell division which results in the formation of gametes.
