Question

Assertion (A): Ethylene indirectly reduces water absorption in plants.
Reason (R): It prevents the formation of root hairs.

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is not the correct explanation of A
• C. Only A is correct
• D. Both A and R are incorrect

Answer 1

The correct option is D Both A and R are incorrect

Ethylene promotes the growth of roots and also increases the formation of root hairs. The root hairs are tiny hair-like structures present on the roots that increase the surface area of the root. Because of the increased surface area of the root, water absorption of the plant also increases. Hence, both assertion and reason are incorrect.
