Question

Which events are necessary for photosynthesis​

Answer 1

The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.

Answer 2

Explanation:

for photosynthesis the events necessary are :-

1. absorption :- the light energy is absorbed
2. conversion of light :- light energy is get converted into hemical energy and splitting of water molecules into hydrogen and oxygen.
3. reduction:- carbon dioxide is get reduced to carbohydrates.

The above steps may or may not take place one after the other immediately, e.g. desert plants take up carbon dioxide at night and prepare an intermediate compound.

This intermidiate compound is acted upon by energy absorbed during the day by chlorophyll.
