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.

1.1 Mode of Nutrition in Plants

Plants have the unique ability to produce their own food, setting them apart from other living beings.

They utilize sunlight, minerals, water, and carbon dioxide present in their surroundings to prepare their food.

The process by which plants convert these raw materials into food is known as photosynthesis.

During photosynthesis, plants use chlorophyll, a green pigment found in their cells, to capture sunlight energy.

The captured sunlight energy is then used to convert carbon dioxide and water into glucose, a form of sugar.

Glucose serves as the primary source of energy for the plant's growth, development, and metabolic processes.

Along with glucose, plants also produce oxygen as a byproduct of photosynthesis, which is released into the atmosphere.

The minerals absorbed by plants from the soil play a crucial role in their growth, as they provide essential nutrients necessary for various cellular activities.

These nutrients not only support plant growth but also aid in repairing damaged body parts.

Through their autotrophic mode of nutrition, plants demonstrate their self-sufficiency in obtaining energy and nutrients from their environment.

1.2 Photosynthesis- Food Making Process in Plants

Leaves are considered food factories in plants, synthesizing food for all parts of the plant.

Different body parts transport raw materials to the leaves.

Roots absorb water and minerals from the soil and transport them to the leaves through vessels.

Stomata, tiny pores on the leaves, absorb carbon dioxide, and their opening and closing are controlled by guard cells.

Chlorophyll, present in all leaves, is responsible for the green color and traps sunlight for photosynthesis.

Photosynthesis is the process by which plants produce food using sunlight, carbon dioxide, and water.

Photosynthesis is essential for maintaining life on Earth as it provides food for plants, which is the basis of the food chain.

During photosynthesis, chlorophyll uses sunlight, water and carbon dioxide to produce carbohydrates.

The equation for photosynthesis is : 

$\text{Carbon dioxide + water }\xrightarrow[\text{Sunlight}]{\text{Chlorophyll}}\text{ Carbohydrate + oxygen}$

Oxygen is released as a byproduct of photosynthesis, and the carbohydrate formed is converted to starch.

Starch in leaves indicates the occurrence of photosynthesis.

Plants with yellow, red, or multicolored leaves also perform photosynthesis as chlorophyll is present in these leaves.

Algae in stagnant water bodies, indicated by green slimy patches, also perform photosynthesis using chlorophyll.

Cells, the building blocks of every living body, play various functions, including gaseous exchange during photosynthesis.

Stomata control gaseous exchange, and their opening and closing are regulated by guard cells.

1.3 Other Modes of Nutrition in Plants

Not all plants contain chlorophyll:

Some plants, like Cuscuta, do not have chlorophyll.

Cuscuta is a yellow tubular plant that twines around the stems of other plants.

Heterotrophic nutrition in non-chlorophyll-containing plants:

Plants without chlorophyll obtain their food through heterotrophic nutrition.

They acquire nutrients from other living organisms.

Host-parasite relationship:

Non-chlorophyll-containing plants rely on a host plant to obtain nutrients.

When these plants deprive the host of its valuable nutrients, they are called parasites.

Plants as parasites:

We often associate parasites with insects and animals, but plants can also be parasites.

Non-chlorophyll-containing plants that depend on other organisms for nutrition are considered parasitic.

Insectivorous plants:

Some plants, like the pitcher plant, have pitcher-shaped structures formed from modified leaves.

The pitcher plant captures insects (prey) when they fall into the pitcher.

Hairs directed downwards inside the pitcher prevent the insects from escaping.

These plants are known as insectivorous plants as they consume insects for nutrition.

1.4 Saprotrophs

Mushroom's Nutritional Mode: Unlike plants, mushrooms do not contain chlorophyll and cannot perform photosynthesis. Instead, they obtain their food through a process known as saprophytic nutrition. This involves secreting digestive juices and chemicals onto decaying or dead organic matter, extracting nutrients from them. Mushrooms are considered saprotrophs in this nutrition mode.

Fungi Growth on Various Surfaces: Fungi can be found growing on different surfaces such as leather, pickles, bread, and other materials that are kept in hot and humid conditions for extended periods. These fungi thrive on the presence of moisture and organic matter, aiding in their growth and decomposition process.

Fungi in Rainy Seasons: Rainy seasons often see an increase in the population of saprotrophic fungi. These fungi play a role in the spoilage of food and clothing during this time. Fungal spores, which can travel through the air, settle on wet surfaces and germinate, leading to fungal growth and the subsequent spoilage of items.

Symbiotic Relationships: In certain relationships between organisms, both parties benefit from their association. One example is the close association between certain fungi and plant roots. These fungi, known as mycorrhizae, derive nutrients from the plants while providing them with nitrogen in return. This mutualistic relationship benefits both organisms involved.

Lichens: Lichens are another example of a symbiotic relationship involving fungi. In lichens, fungi and algae coexist. The algae produce food through photosynthesis, while the fungus provides water, minerals, and a protective structure for the algae. This partnership allows both organisms to thrive in various environments.

1.5 How Nutrients are Replenished in the Soil

If plants use all the minerals and nutrients from the soil, the levels of these nutrients in the soil are supposed to go down. To replenish the nutrient content of the soil, farmers often add manures and fertilizers to the soil. In this way, the nutrients are replenished, and it will support the continued growth of plants on this soil.

In general, soils require plenty of nitrogen for their growth. After each harvest, the soil gets devoid of nitrogen. To have further plantation on these soils, farmers often grow leguminous crops that can increase the nitrogen content of the soil. These leguminous crops like pulses, grams, dal, etc. are in a symbiotic relationship with a bacteria called rhizobium, which fixes atmospheric nitrogen into the soil. The bacteria obtain food and shelter in return from the plants. Growing leguminous crops in the field reduces the need to add nitrogen-containing artificial fertilizers to the soil.

In this CBSE Class 7 Science Chapter 1 nutrition in plants, you learned about plants that are autotrophs. You also learned about different nutrition modes amongst plants like heterotrophic, saprophytic, parasitic, insectivorous and symbiotic.

Facts that Matter

All organisms take food and utilize it to get energy for growth, maintenance and various life processes.

Based on the mode of getting food, organisms are classified as autotrophs and heterotrophs.  

Autotrophs prepare their own food using simple inorganic materials like carbon dioxide and water. 

The essential requirements for photosynthesis are chlorophyll and sunlight.

Heterotrophs are organisms that cannot make food on their own and so they depend on autotrophs directly or indirectly for food.

Parasitic, saprophytic, insectivorous and symbiotic are the different modes of heterotrophic nutrition in plants.

Plants like Cuscuta are parasites as they take nutrition from the host plant.

Saprotrophs like Fungi obtain nutrition from dead and decaying organic matter. 

Symbiotic relationship between Rhizobium and legumes helps in enriching the soil of the nitrogen that was lost.

Leaves of the plants prepare the food so they are called the food factory of the plant.

The important components of food are carbohydrates, fats, proteins, vitamins and minerals. 

The Sun is the fundamental source of energy for all living organisms.

FAQs on NCERT Solutions for Class 7 Science Chapter 1 - Nutrition In Plants

1. How does the fungus get its nutrition?

Fungus is a saprotroph. Its mode of nutrition is called the saprotrophic mode of nutrition. It takes its food from dead and decaying organic matter. The digestive juices of fungus convert the dead materials into a soluble form that gets absorbed.

2. Explain the process of how nutrients are replenished in the soil.

The plants absorb mineral nutrients from the soil. The fertilizers and manures containing various nutrients like nitrogen, potassium, and phosphorus need to be added from time to time to enrich the soil. Nitrogen gas is available in large amounts but plants cannot use it directly from the air. The bacterium Rhizobium lives in the roots of the leguminous plants. Rhizobium bacteria convert the non-usable form of nitrogen. In this way, the nutrients are replenished in the soil by using fertilizers and manures, and by sowing leguminous plants.

3. Explain the mechanism of eating insects by a pitcher plant.

The leaves of the pitcher plants are tailored into a pitcher-like structure. The tip of the leaves forms a lid that can open and close the mouth of the pitcher-like structure of the leaves. There is hair inside the pitcher, which is directed downwards. When an insect lands in the pitcher, it gets entangled in the hair. The pitcher secretes some digestive juices that help the plant digest the insect. Such insects eating plants are insectivorous plants. These plants do not get all the necessary nutrients from the soil. So, they are called partial heterotrophs.

4. Summarize briefly Chapter 1 of Class 7th Science NCERT Textbook?

In Class 7 Chapter 1 Nutrition in Plants, students are introduced to topics related to plants and how they get nutrition for themselves. The concepts covered in these topics include the photosynthesis process, chlorophyll and stomata. The chapter also teaches other modes of nutrition in insectivorous plants. 

Students also learn how nutrients are replenished in the soil and how atmospheric nitrogen is fixed in the soil through a bacterium called Rhizobium.

5. Why should we grow crops inside greenhouses?

Exercise Questions

1. Why do organisms take food?

All organisms require energy for their life processes. Plants prepare their food and acquire nutrients from abiotic components like soil, air, water and sunlight. On the other hand, animals need to get food from either plants or other animals to obtain nutrients; hence, animals need to take food to acquire nutrients and energy.

2. Distinguish between a parasite and a saprophyte.

3. How would you test the presence of starch in leaves?

Take two potted plants of the same kind. Keep one in the dark for 72 hours and the other in the sunlight. Perform the iodine test with the leaves of both plants as given below. Now, leave the pot, which was earlier kept in the dark, undisturbed for 3–4 days and perform the iodine test again on its leaves.

Iodine test:

Put iodine solution on the leaf.

Observation:

Blue-black colour will be observed on the leaves of the plant kept in sunlight, which indicates the presence of starch.

Blue-black colour will not be observed on the leaves of plants kept in the darkroom. This indicates the absence of starch.

4. Give a brief description of the process of synthesis of food in green plants.

Green plants use a process called photosynthesis to prepare their food. The process is as follows

• Water is taken from the roots of the plant, and it is transported to the leaves of the plant.
• Carbon dioxide from the air enters the leaves through pores called stomata. This diffuses the cell containing chlorophyll.
• Water molecule is broken down into Hydrogen and Oxygen with the help of sunlight.
• Hydrogen combines with Oxygen and Hydrogen to form carbohydrates.
• Photosynthesis is represented by the following equation.

5. Show with the help of a sketch that plants are the ultimate source of food.

6. Fill in the blanks.

(a) Green plants are called _________________ since they synthesise their own food.

(b) The food synthesised by plants is stored as _________________.

(c) In photosynthesis, solar energy is absorbed by the pigment called ___________.

(d) During photosynthesis, plants take in ______________________ and release __________________ gas.

(a) Green plants are called autotrophs since they synthesise their food.

(b) The food synthesised by plants is stored as starch .

(c) In photosynthesis, solar energy is absorbed by the pigment called chlorophyll.

(d) During photosynthesis, plants take in carbon dioxide and release oxygen gas.

7. Name the following.

i) A parasitic plant with a yellow, slender and branched stem.

ii) A plant that is partially autotrophic.

iii) The pores through which leaves exchange gases.

ii) Pitcher plant

iii) Stomata

8. Tick the correct answer.

(a) Cuscuta is an example of:

(i) autotroph

10. Mark ‘T’ if the statement is true and ‘F’ if it is false.

(i) Carbon dioxide is released during photosynthesis. (T/F)

(ii) Plants which synthesise their food are called saprotrophs. (T/F)

(iii) The product of photosynthesis is not a protein. (T/F)

(iv) Solar energy is converted into chemical energy during photosynthesis. (T/F)

11. Choose the correct option from the following:

Which part of the plant takes in carbon dioxide from the air for photosynthesis?

(i) Root hair (ii) Stomata (iii) Leaf veins (iv) Petals

The answer is (ii) Stomata

12. Choose the correct option from the following:

Plants take carbon dioxide from the atmosphere mainly through their:

(i) roots (ii) stem (iii) flowers (iv) leaves

The answer is (iv) leaves
