Answer 1

The correct option is C

Both (a) and (b)

The correct option is option C.

An explanation for the correct answer:

• Stomata are small pores in the epidermis of leaves, stems, and other plant organs.
• Stomata allow gases (CO2 and O2) to exchange with the atmosphere. The stomata are the pores on the leaf surface that allow water to evaporate. As a result, the stomata contribute to the process of transpiration.

The explanation for the incorrect options:

Option A:

• Stomata help in transpiration as well as the exchange of gases.

Option B:

• Stomata help in the exchange of gases as well as transpiration.

Option D:

• Stomata help in transpiration as well as the exchange of gases.

Therefore, the stomata help in transpiration and gaseous exchange with the atmosphere.
