Question

1. How do roots absorb water and how does water got transported from root hair to
primary root?
​

Answer 1

Answer:

hi friend ,

Explanation:

They absorb water by the process of osmosis. ... So the water moves into the root hairs through osmosis. Thus the cell of root hairs become turgid and exert pressure on the adjacent cells. This pressure is called root pressure

Answer 2

Answer :

The root hair cell absorbs water from the soil by imbibition and osmosis. Absorption of water takes place with the help of root hairs.

There are two major ways by which water is absorbed in the root system:

Passive absorption of water :

$\bigstar$ Absorption of water caused due to the forces generated in the aerial parts of the plant body is called passive absorption of water.

$\bigstar$ Absorption of water by passive mechanism involves two important phenomena, water potential gradient and transpiration pull.

Active absorption of water :

$\bigstar$ Absorption of water caused due to the forces generated in the root itself is called active absorption. It is also known as absorption of water by the root.
