a) Definition
b) Equation c) Necessary conditions
d) Products formed
Class 7

Answer 1

Answer:

a) the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

b)6CO2 + 6H2O → C6H12O6 + 6O2.

c)To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food

d) The products of photosynthesis are glucose and oxygen.

Answer 2

Answer:

1.photosynthesis is a process by which green plants and some other organisms use sunlight to synthesis nutrients from water and carbon dioxide.

2.carbon dioxide+water_ >glucose+oxygen+water it can be written as 6CO2 + 6 H2O_>C6H12O6+6O2.

3.water, sunlight, carbon dioxide and chlorophyll.

4.Complex chemical substance such as carbohydrates are the products of photosynthesis
