Detailed explanation-1: -Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis.

Detailed explanation-2: -Osmosis is a type of diffusion specifically for water molecules moving across a semi-permeable membrane.

Detailed explanation-3: -Diffusion of water through a semipermeable membrane is called imbibition.

Detailed explanation-4: -The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food colouring is added to a glass of water, where eventually, the entire water content becomes coloured.
