Question

What is the difference between endosmosis and exosmosis ?

Answer 1

1. If a cell is placed in a hypotonic solution, then the water moves inside a cell and swells. This movement of water inside a cell is known as endosmosis.
2. If a cell is placed in a hypertonic solution, then the water moves out of the cell and the cell becomes flaccid. This movement of water out of the cell is known as exosmosis.

Endosmosis	Exosmosis
Water moves into the cell.	Water moves out of the cell.
Occurs when cells are placed in hypotonic solution.	Occurs when cells are placed in hypertonic solution.
Cells may swell.	Cells may shrink.
Water potential of the surroundings is higher than that of the cytosol.	Water potential of the surroundings is less than that of the cytosol.
