Question

Ethylene promotes water absorption by increasing the root's absorption surface. It promotes:

• A. Premability of cell membrane
• B. Rormation of root hairs
• C. Concentration of cell sap
• D. All of these

Answer 1

Answer: (D)

All of these

Ethylene promotes water absorption by increasing the root's absorption surface. It promotes the elongation of the root hairs and the root itself and it is also responsible for increasing the cell permeability in some cases. It has also been observed to increase the osmotic pressure and the concentration of cell sap.

So, the correct answer is 'all of these'.
