Question

How does the closing of the stomata limit photosynthesis?

Answer 1

The correct answer will be- no exchange of gases will reduce efficiency of photosynthesis.

Step-by-step explanation:

The stomata are the pores on the leaves which helps the plant in gaseous exchange and transpiration.

The property of gaseous exchange is dominantly used in the photosynthesis as the process requires carbon dioxide which is inhaled from the environment by the plants through stomata as well oxygen is exhaled from the plants through these stomata.

If stomata will be closed, it will directly affect photosynthesis as there will be no gaseous exchange of carbon dioxide and the efficiency of the process will be declined

Thus, no exchange of gases will reduce the efficiency of photosynthesis will be the correct answer.

Answer 2

Stomata opens to intake carbon dioxide in the presence of light there by allowing the process of photosynthesis during the day time.

Step-by-step explanation:

The gaurd cell of the stomata play an important role in regulating the photosynthesis. During the day time, the stomata is open which allows intake of carbon dioxide from atmosphere. Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
