Question

Assertion: Root pressure can provide a modest pull in the overall water transport in plants.

Reason: It does play an important role in water movement in tall trees.

• A. if both A and R are true and R is the correct explanation of A
• B. if both A and R are true but R is not the correct explanation of A
• C. if A is true but R is false
• D. if both A and R are false.

Answer 1

The correct option is D

if both A and R are false.

Transpirational pull provides the pull during the ascent of sap and root pressure has no effect on the same in tall trees. Root pressure is a positive pressure which pushes water up in small plants.
