Question

Stomata having pores bounded by a single ring shaped guard cell are found in the

• A. Leaf of ferns.
• B. Pinnule of Cycas.
• C. Capsule of Funaria.
• D. All of the above.

Answer 1

The correct option is C Capsule of Funaria.

The epidermal tissue in plants is made up of several cells such as epidermal cells, guard cells, subsidiary cells, and trichomes. On the epidermis of the plant leaf and stems are present stomata which are small opening surrounded by guard cells and are an important component of photosynthesis as this helps in exchange of gases and water vapor between the outside air and leaf interiors. While guard cells are generally moon shaped and found in pairs surrounding the stomatal pore, the outermost epidermis of the capsule of Funaria plants has one annular guard cell with a central pore. Thus, the correct answer is option C.
