Question

how does transpiration help ascent of SAP​

Answer 1

Answer:

Transpiration creates a suction force due to which water from the nearby tissues enters into the Xylem, which eventually helps in the upward movement or Ascent of sap.

Answer 2

Ascent of Sap

Explanation:

• Ascent of sap is the movement of water and minerals from the roots to the aerial parts of the plant through xylem tissue.
• Transpiration pull due to evaporation of water from the cells presents on the surface of the leaves (transpiration) a vacuum space is created.
• Thus transpiration helps in the ascent of sap by producing a suction force acting from the bottom of the plant.
