Question

Write the specific feature of the cell sap of root hairs which helps in absorption of water.

Answer 1

Endosmosis:

1. It is a type of osmosis, in which water enters the cell from the surrounding.
2. Here, endosmosis is seen as water enters the root hairs from the soil.
3. This feature helps in the absorption of water in plants through roots.

Cell sap of root hairs:

1. The osmotic concentration of cell sap of root hairs is higher than that of its surrounding soil.
2. For this reason, water from the soil enters the root hair cells through the process of osmosis (more specifically endosmosis).
