Question

Name the phenomenon by which raisins placed in water swell up.

Answer 1

Endosmosis.

• The raisins are swelled up when placed in pure water due to endosmosis.
• The movement of water from the outside to the inside of a cell through the osmosis process is known as endosmosis.
• This happens because the solute concentration of the surrounding solution is less than that inside the cytoplasm.
