Question

Plasma membrane is permeable to water. How does a cell show endosmosis or exosmosis?

Answer 1

The movement of water into and outside the cell depends on the concentration of solutes present in the water. In case water inside the cell has low solute concentration than the water present outside the cell, the water will move from the cell to the outside. This is called exosmosis. In case the solute concentration outside the cell is lesser than the solute concentration inside the cell, water will move into the cell. This is called endosmosis.
