Question

Study the following lists.
List-I List-II
(A) Henry Dixon (I) Bioelectrical responses
(B) Slatyer and Taylor (II) Cohesion-Tension theory
(C) Levitt (III) Active proton concept
(D) J.C.Bose (IV) Water potential
(V) Term 'Physiology'
The correct match is

• A. (A)- (V), (B)- (II), (C)- (I), (D)- (III)
• B. (A)- (II), (B)- (III), (C)- (IV), (D)- (V)
• C. (A)- (II), (B)- (IV), (C)- (III), (D)- (I)
• D. (A)- (V), (B)- (I), (C)- (IV), (D)- (II)

Answer 1

The correct option is C (A)- (II), (B)- (IV), (C)- (III), (D)- (I)

Henry Dixon postulated Cohesion Tension theory which is based on inter molecular attraction that explains the process of water flow against the force of gravity through the xylem of plants. In 1960, water potential term was coined by Slatyer and Taylor. In 1974, Levitt proposed active potassium theory and observed that proton ion uptake by guard cells, chloroplasts takes place with the help of ATP. J. C. Bose observed bioelectrical responses in plants.

Thus, the correct answer is option C.
