Question

What happens during the second stage of photosynthesis?

Answer 1

Photosynthesis:

1. Photosynthesis is a very important process occurring in all green plants, algae as well as fungi.
2. It is an endothermic process in which a series of reactions occurs by which light energy is converted into chemical energy.
3. Raw materials required are:- Carbon dioxide, water, and sunlight.
4. The gas used up is carbon dioxide. The end product obtained by photosynthesis are glucose and oxygen.
5. Photosynthesis occurs in two stages: Light-dependent reactions and the light-independent reactions.

Light-dependent reactions:

1. These are the reactions occurring during the daytime.

Light-independent reactions:

1. It is also known as Calvin cycle.
2. In the Calvin cycle, carbon dioxide is used to produce glucose.
3. The reaction keeps going on continuously.
