Question

Identify the CORRECT pair with respect to distribution of stomata on leaves.
(A). Epistomatic - on lower epidermis
(B). Amphistomatic - on both surfaces
(C). Hypostomatic - on upper epidermis

• A. Only (B)
• B. (A) and (C)
• C. Only (C).
• D. (A), (B) and (C)

Hint:

Epistomatic means stomata on the upper surface and hypostomatic means stomata on the lower surface.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
Leaves are classified by where their stomata lie: on the upper epidermis, on the lower epidermis, or on both.

Step 2: Check each pair
(A) is wrong because epistomatic leaves have stomata on the upper epidermis. (C) is wrong because hypostomatic leaves have stomata on the lower epidermis.

Step 3: Pair (B)
Amphistomatic leaves have stomata on both surfaces, as in many monocot leaves. So (B) is correct.

Final Answer:
Only pair (B) is correct. \[ \boxed{\text{(A) }\text{Only (B)}} \]
