phenomenon involved with the help of a diagram. Give three
applications of the phenomenon.
​

Answer 1

This process is called endosmosis

Explanation:

The cell has less amount of water than the water outside it's cells, so the water enters the cell.

This is a type of osmosis. It means that the water travels from the medium having more water to the medium having less water.

The walls of raisin(partially dried grapes) consist of semipermeable membrane. When kept in water, they swell as concentration(of water) inside raisin is high. This phenomenon is called 'osmosis'.
