Question

Statements.
(1) Dixon Jolly proposed a cohesion-tension theory for the ascent of sap in plants.
(2) Root pressure accounts in the ascent of sap in small plants.
(3) Food (solutes) translocation is a bidirectional movement mechanism.
(4) Imbibition plays an important role in seed germination.
The correct statement are grouped in

• A. 3 and 4
• B. 1 and 4
• C. 1, 2 and 3
• D. 1, 2, 3 and 4

Answer 1

The correct option is D 1, 2, 3 and 4

All the statements are true.

1. Dixon and jolly proposed a cohesion- tension theory for the ascent of Sap in plants.

2. Root presure accounts for ascent of sap in small plants as this amount of pressure is enough for a few metres of heights.

3. Food translocation through phloem is a bidirectional movement.

4. Imbibition helps the seed absorb water and hence help them in germination and growth.

So the correct answer is '1, 2, 3, and 4'.
