Question

In which of the following plants, stomata are absent?

• A. Cactus
• B. Hydrilla
• C. Lily
• D. All of these

Answer 1

The correct option is B

Hydrilla

The correct option is B.

The explanation for the correct option:

• The structures found in the epidermis of leaves and needles that help plants exchange carbon dioxide and water with the environment are known as stomata.
• In aquatic plants, stomata are absent, so in Hydrilla, stomata are absent.

The explanation for the incorrect options:

Option A:

• The stomata of a cactus are slightly recessed, which shades and shields them from the wind.

Option C:

• Water lilies' stomata are placed on the top surface of their leaves, allowing for maximum air exposure.

Option D:

• Only Hydrilla does not contain stomata.

Therefore, the stomata are absent in the Hydrilla.
