Sir.J.C. Bose proposed which of the following theory to explain the process of ascent of sap?
Options
(a) pulsation theory
(b) relay pump theory
(c) transpiration pull theory
(d) capillary force theory
Correct Answer:
pulsation theory
Explanation:
Sir J.C. Bose proposed the pulsatory theory in 1923 to explain the mechanism of ascent of sap. According to this theory, the inner cortical cells have the ability to generate the electrical impulses which result in rhythmic pulsations. These pulses are responsible for the ascent of sap in the tracheary elements.
