TNSCERT Class 7 General Science Ch2 Nutrition in Plants and Animals

Answer 1

Photosynthesis is a process by which green plants prepare their own food .

During this process, plants absorbs sunlight through their leaves and covert it into food energy by using raw materials from the atmosphere and soil

                        chlorophyll            Starch

Answer 2

Answer:

Photosynthesis is the process by which the plants containing the green pigment 'chlorophyll' build up complex organic molecules from relative simple inorganic ones, using sunlight as an energy source. This process of photosynthesis is very complex.
