In each of the following situations what happens to the rate of photosynthesis?
a] Cloudy days
b] No rainfall in the area
c] Good manuring in the area
d] Stomata get blocked due to dust

Text Solution

Verified by Experts

a] Cloudy days will cause the rate of photosynthesis to decrease due to the low availability of Sunlight.
b] No rainfall in the area will cause the rate of photosynthesis to decrease due to the low availability of water.
c] Good manuring in the area will cause the rate of photosynthesis to decrease due to the improved availability of minerals necessary for plant growth and development.
d] Stomata get blocked due to dust will cause the rate of photosynthesis to decrease due to the disturbed carbon dioxide intake through stomata.
