1. Why do organisms need to take food?
Ans. Living organisms intake food because of
i) getting energy and survival.
ii) growth and development of the body.
iii) the maintenance of their bodies.
2. How is a parasitic plant different from a saprotrophic plant?
Ans.
| PARASITE | SAPROTROPH |
| i) An organism which depends on other organisms for its nourishment and growth is called parasite.> | i) An organism that take nutrients in the form of solution from dead and decaying organic matter is called saprotroph. |
| ii) Parasite gets its nourishment from a living organism known as host.> | ii) Saprotroph gets its nourishment from dead and decaying organic matter.> |
| iii) Chlorophyll may be present > Eg : Cuscuta (Amarbel), rafflesia etc.> | iii) Chlorophyll is absent> Eg : Fungi and some bacteria.> |
3. What method can be used to check if starch is present in a leaf?
Ans. i) Take two healthy green potted plants of the same type.
ii) Keep one potted plant in a dark room for one or two days in order to remove all the starch from the leaves.
iii) Keep the other plant in sunlight.
iv) Now, take one leaf from each potted plant and put a few drops of iodine solution on them. Then note down the observation.
v) No blue black colour will be observed on the leaves of the plant kept in the dark room. This indicates the absence of starch.
vi) Blue black colour will be observed on the leaves of the plant kept in sunlight. This indicates the presence of starch.
4. How do green plants make their own food? Explain briefly.
Ans. i) The process of synthesis of food in green plants is called photosynthesis.
ii) During photosynthesis, chlorophyll containing cells of leaves and other parts of a plant, in the presence of sunlight, use carbon dioxide and water to synthesise food materials. Carbon dioxide + water " Carbohydrates + Oxygen

Class 7 Science chapter 1 Nutrition in Plants is interesting as it introduces students to the world of plants around us. The CBSE syllabus covers several projects that will help students to enjoy this learning process. The curriculum also deal with new terminology and concepts, which help to look forward for this Chapter. In this Chapter, students came to know about many new concepts which deals with plants and how they get nutrition for themselves, they also deal with about photosynthesis-process of preparation of food in plants, chlorophyll, stomata.
Several other modes of nutrition in plants like insectivorous plants. This chapter deal with the basic of plants nutrients, how plants make their food, but studying this Chapter in depth will further help the students to understand the concepts of botany in higher standards. Therefore student must prepare to note so that they can quickly revise the notes while revising the Chapter for the exams.

Nutrition in Class 7 Science Chapter 1 refers to the process by which plants and other organisms obtain and utilize food for energy, growth, and maintenance.
The first chapter of Science Class 7 is Nutrition in Plants, which covers how plants obtain nutrients through various processes, including photosynthesis.
Plants get nutrition primarily through photosynthesis, where they use sunlight, carbon dioxide, and water to produce glucose and oxygen. Some plants also obtain nutrients from the soil.
Plants need nutrients like carbohydrates, proteins, fats, vitamins, minerals, and water for healthy growth and development. These nutrients help them stay strong and carry out life processes.
Green plants are called autotrophs or producers because they can produce their own food through the process of photosynthesis.
