Question

Explain any three factors that affect photosynthesis. [3]​

Answer 1

Answer:

I think the three factors that affect is sun light, water,soil

Answer 2

Answer:

The process of photosynthesis is affected by

Carbon dioxide

The amount of carbon dioxide in the atmosphere is 0.03%. If the amount of CO2 increases by up to 0.1%, the rate of photosynthesis also increases. But, the rate of photosynthesis decreases, if the amount of CO2 increases beyond 0.1%.

Water

Water is a very important raw material for photosynthesis. A slight decrease in the amount of water causes the closing of stomata. This results in less absorption of CO2 in leaves, hence the process of also slows down..

Sunlight

Photosynthesis does not take place in the dark. If the intensity of sunlight is increased slowly, the rate of photosynthesis increases up to a certain point (called saturation point). If the intensity of sunlight increases beyond the saturation point, then photosynthesis slows down.

Oxygen

It is observed that a small quantity of oxygen is essential for photosynthesis, whereas a high quantity of oxygen slows down the rate of photosynthesis.

Temperature

At low temperature the rate of photosynthesis is slow. As the temperature is increased, the rate of photosynthesis also increases up to a certain point. But a high increase in temperature slows down the rate of photosynthesis.
