Question

Osmotic theory of active water absorption was given by

• A. Keller
• B. Bennet-Clark et al
• C. Atkins
• D. Kramer

Answer 1

The correct option is C Atkins

Water absorption takes place through root. There are two theories to explain the mechanism of water absorption. One is passive absorption and the other is active absorption. Osmotic theory of active water absorption was given by Atkins and Priestley. According to this theory, water is absorbed due to osmotic difference between soil water and tonoplasm. Water moves from soil to root xylem along the increasing gradient of suction pressure.

Thus, the correct answer is option C.
