Question:
Assertion (A): Trichomes help in preventing water loss due to transpiration.
Reason (R): The specialized cells near the guard cells together constitute stomatal apparatus.
Assertion (A): Trichomes help in preventing water loss due to transpiration.
Reason (R): The specialized cells near the guard cells together constitute stomatal apparatus.
Reason (R): The specialized cells near the guard cells together constitute stomatal apparatus.
Show Hint
Trichomes reduce water loss; stomatal apparatus controls gas exchange — they serve different functions.

- (A) and (R) are true. (R) is correct explanation for (A)
- (A) and (R) are true. But (R) is not correct explanation for (A)
- (A) is true, but (R) is false
- (A) is false, but (R) is true

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Assertion (A): True — Trichomes are hair-like outgrowths that reduce transpiration by reflecting sunlight and trapping moisture.
Reason (R): True — The stomatal apparatus includes guard cells and surrounding subsidiary cells.
But, R is not the reason for A — Trichomes and stomatal apparatus are unrelated structures.
So, both statements are true, but (R) is not the correct explanation of (A).
