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

(d) Stomata get blocked due to dirt.


(a) Cloudy Days: Photosynthesis is reduced due to low light intensity.

(b) No Rainfall: Rate of photosynthesis decreases due to wilting of leaves, closure of stomata and reduced availability of hydration.

(c) Good Manuring: Rate of photosynthesis increases as good manuring increases soil fertility by providing more minerals, moisture and aeration.

(d) Blocked Stomata: It decreases the rate of photosynthesis by reducing gaseous exchange and non-cooling of leaves due to reduced transpiration.
