Question

Based on Distribution and Arrangement of STOMATA in leaves, Match List-I with List-II:

Choose the correct answer from the options given below:

• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)

Hint:

Floating aquatic plants like water lilies (Nymphaea) can only exchange gases with the atmosphere via their upper surface.
Therefore, they have stomata only on their upper leaf surface (Epistomatic).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Stomatal distribution on leaf surfaces varies depending on plant habitat, leaf orientation, and species-specific adaptations.

Step 2: Detailed Explanation:
1. Present on the lower surface only (Hypostomatic Apple type) (A):
This adaptation reduces water loss in tree species like Apple and Mulberry (IV).
2. Present more on the lower surface and less on the upper surface (Potato type) (B):
This pattern is typical of many herbaceous dicots like Potato and Tomato (III).
3. Equally distributed on both upper and lower surfaces (Amphistomatic Oat type) (C):
This is common in vertically oriented leaves of monocots like Maize and Rice (I).
4. Present only on the upper surface (Epistomatic Water lily type) (D):
This is characteristic of floating hydrophytes like Nelumbo and Nymphaea, where the lower surface remains in contact with water (II).
Matching the pairs: (A) - (IV), (B) - (III), (C) - (I), (D) - (II).

Step 3: Final Answer:
The correct matching sequence corresponds to Option 2.
