Match List I with List II
Choose the correct answer from the options given below:
| List I (Types of stomata) | List II (Group of plants where they occur) |
|---|---|
| (A). Epistomatic | (I). Xerophytes |
| (B). Hypostomatic | (II). Mesophytes |
| (C). Amphistomatic | (III). Hydrophytes |
Choose the correct answer from the options given below:
Options
- A(A) - (I), (B) - (II), (C) - (III)
- B(A) - (II), (B) - (I), (C) - (III)
- C(A) - (III), (B) - (I), (C) - (II)
- D(A) - (III), (B) - (II), (C) - (I)
Correct answer
D. (A) - (III), (B) - (II), (C) - (I)
Step-by-step solution
Based on the distribution of stomata on the leaf surfaces, leaves are classified into different types that correlate with their ecological adaptations:
Epistomatic leaves have stomata exclusively on the upper (adaxial) epidermis. This adaptation is characteristic of floating hydrophytes (like water lilies), as their lower leaf surface is in contact with water and cannot facilitate direct gas exchange with the atmosphere. Thus, (A) matches with (III).
Hypostomatic leaves bear stomata mainly or entirely on the lower (abaxial) epidermis. This is the typical condition for dorsiventral leaves of dicotyledonous mesophytes, helping them minimize excessive transpirational water loss caused by direct exposure to sunlight. Thus, (B) matches with (II).
Amphistomatic leaves possess stomata on both the upper and lower surfaces. While found in monocot mesophytes, this is a very prominent adaptive feature of isobilateral leaves in many xerophytes. It allows them to maximize carbon dioxide uptake for photosynthesis during the brief periods when water is available and stomata are open. Thus, (C) matches with (I).
The correct matching sequence is (A) \rightarrow (III), (B) \rightarrow (II), and (C) \rightarrow (I).
