Question

describe cohession,tension theory of ascent of sap.​

Answer 1

Answer:

Cohesion tension theory says that the movement of water in the upwards direction against gravity is guided by the attractive forces between the particles of water which is known as cohesion and thus gives rise to surface tension which pulls the water upwards from the root through the xylem and this is aided by ...

Answer 2

Explanation:

• Cohesion tension theory says that the movement of water in the upwards direction against gravity is guided by the attractive forces between the particles of water which is known as cohesion and thus gives rise to surface tension which pulls the water upwards from the root through the xylem and this is aided by Transpiration pull and capillary action of water. This is the main mechanism of transport of water in plants.
