Question

What will happen to the rate of photosynthesis in a plant under the following circumstance?
No rainfall in the area for a considerable time.

Answer 1

Photosynthesis is a process by which green plants prepare their own food with the help of oxygen, carbon dioxide, sunlight, water etc. No rain in the area means no availability of water as per definition water is essential for green plants for photosynthesis. So, the rate of photosynthesis decreases.
