Question

Three events which occur during the process of photosynthesis

Answer 1

The three events that occur during the process of photosynthesis are:

(i) Absorption of light energy by chlorophyll.

(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.

(iii) Reduction of carbon dioxide to carbohydrates.

Answer 2

1) The exchange of gasses is done.
2) Absorption of light energy or solar energy by green colour pigment called chlorophyll.
3) The process of photosynthesis first produces a simple carbohydrate called ‘glucose’.
