questions on photosynthesis for class 7

The process of photosynthesis takes place in the leaves of a plant. The oxygen gas produced in the leaves during photosynthesis goes out into air through the same stomatal pores. chlorophyll. (a) Four cell organelles. The simplest food synthesised by the plants by photosynthesis is, a simple carbohydrate called glucose. Why do leaves generally look green ? (1)Photosynthesis by plants provides food to animals (including human beings): The survival of animals (including human beings) depends on the food made by plants by photosynthesis. Photosynthesis is important for the existence of life on this earth. This green layer is formed by the growth of tiny green plant-like organisms called algae . Chlorophyll absorbs light energy from the sun and supplies this energy to the leaves to enable them to carry out photosynthesis for making food. Water and minerals present in the soil are absorbed by the roots of a plant and transported to its leaves through interconnected pipe like xylem vessels present throughout the roots, stem, branches and leaves of the plant.

Potato and carrot plants store a lot of starch in their roots. Chlorophyll and sunlight are notrequired. 4) The role of Sunlight in photosynthesis  – The sunlight supplies energy for the food making process called photosynthesis. The plants also need minerals to make foods other than carohydrates. (5)The synthesis of food (or making of food) occurs in the leaves of a plant, so leaves are the food factories of a plant. Carbon dioxide and oxygen. Those organisms which can not make food themselves by the process of photosynthesis and take food from green plants or animals, are called heterotrophs (and their mode of nutrition is called heterotrophic). Our body cannot make food from carbon dioxide and water present around us by the process of photosynthesis (like plants do) because our body does not have the green pigment called. Question 3 Name the pores through which leaves exchange gases? The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. No animal can survive without oxygen as it is needed for respiration. MCQ Questions for Class 7 Science with Answers were prepared based on the latest exam pattern.
