Question

Transpiration pull is one of the causes responsible for the ascent of sap.

• A. True
• B. False

Answer 1

The correct option is A True

Transpiration Pull:

1. A transpiration pull can be precisely defined as a physiological process of a plant in which a pulling force is generated within the xylem tissue.
2. The upward migration of water into xylem vessels is aided by this force.
3. The water loss in the form of vapors via the leaves, shortly called transpiration, is noted during this phase.

Ascent of Sap:

1. The upward transport of water and minerals inside the xylem tissue of plants from the root to the upper section of the plant body is known as the ascent of sap.
2. As transpiration pull helps in the upward migration of water inside the xylem tissue, it is one of the factors responsible for the ascent of sap.

Final Answer: The given statement ‘Transpiration pull is one of the causes responsible for the ascent of sap’ is true.
