Question

Select the correct option:

Stomata are distributed more on the lower surface than on the upper surface in

• A. Equifacial leaf
• B. Bifacial leaf
• C. Unifacial leaf
• D. Both A and B

Answer 1

Answer: (B)

Bifacial leaf

- In dorsiventral/ dicotyledenous/ bifacial leaf the abaxial epidermis ( Lower surface) generally bears more stomata than the adaxial epidermis (Upper surface). The latter may even lack stomata.

-In an Isobilateral/monocotyledonous leaf, the stomata are present on both the surfaces of epidermis equally.

So, the correct answer is 'Option B- Bifacial leaf'.
