Question

Primitive types of stomata are found in the

• A. Leaves of moss plants
• B. Apophysis of capsule
• C. Axis of the moss plant
• D. All of these

Answer 1

The correct option is B

Apophysis of capsule

The correct option is B.

Explanation for the correct option:

1. Stomata refer to the small openings in plant membranes through which gas and water transportation occur.
2. Primitive forms of stomata are visible in the spore-bearing capsules of mosses.
3. These stomata are present on the epidermal layers of the leaves, stems, or other vegetative parts.
4. In the case of liverworts, this takes place through the pores.
5. But in the case of hornwort and the true mosses, this is just through the stomata on the capsule of the sporophyte.

Explanation for the incorrect options:

Option A:

1. Mosses belong to the group of land plants called Bryophyta and are non-vascular plants.
2. They are herbaceous (non-woody) tiny plants (a few centimeters tall) that primarily absorb water and nutrients via their leaves and use light and carbon dioxide to produce food through photosynthesis.

Option C:

1. Stomata are observed to be absent in the axial region in mosses.
2. Hence, this option is incorrect.

Option D:

1. Stomatal pores are observed only in the capsules of mosses.
2. Hence, this option is incorrect.

Final answer: Primitive types of stomata are found in the apophysis of the capsule.
