Question

Ethylene promote water absorption by increasing root absorption surface. It promote

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

Answer 1

The correct option is A Premability of cell membrane

Ethylene promotes the growth of root hairs. This increases the surface area of roots, which in turn, helps enhance oxygen absorption from spaces between soil particles and thereby increase absorption. So, the correct option is 'Formation of root hairs'.
