Question

List the three events that occur during the process of photosynthesis. Explain the role of stomata in this process

Answer 1

The three 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.

Reduction of carbon dioxide to carbohydrates.

Role of stomata: Tiny openings in leaves called stomata. These help in the gaseous exchange between the plant and its atmosphere. The gas exchange that occurs when stomata are open facilitates photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere through the stomata and oxygen is released as a waste product. Both photosynthesis and the gas exchange that powers it are essential to the plant's survival.
