Question

Pulsation theory was proposed by

• A. Godlewski
• B. Jagadish Chandra Bose
• C. Dixon and Joly
• D. Arthur

Answer 1

The correct option is B Jagadish Chandra Bose

Sir J.C. Bose proposed a theory of ascent of sap known as pulsation theory. The pulsation theory states that water is absorbed by the plants due to the metabolic activity of living cells which are in constant state of rythmatic pulsation. But it was not accepted as water can be passively absorbed by the roots even the cells were dead.

So, the correct answer is option B.
