Question

Assertion (A):- Stomata are tiny pores present on the surface of the leaf.
Reason (R):- Gaseous exchange take place in plants through Stomata.
(a) Both (A) and (R) are true and (R) is the correct explanation of assertion.
(b) Both (A) and (R) are true but (R) is not the correct explanation of assertion.
(c) (A) is true but (R) is false.
(d) (A) is false but (R) is true. ​

Answer 1

Answer:

Option A is the correct answer.

Explanation:

In botany, a stoma, also called a stomata is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening

Answer 2

Answer:

(a) Both (A) and (R) are true and (R) is the correct explanation of assertion.

Explanation:

Assertion:

Stomata are tiny, microscopic pores crucial for photosynthesis present in the surface of the leaves.

Reason:

The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through stomata.

Therefore, Both (A) and (R) are true and reason is the correct explanation of assertion.
