(ii) Hypotonic solution is the solution that possesses lower osmotic concentration and higher solvent concentration as compared to another solution.
(iii) Isotonic solution is the solution that has the same concentration, osmotic as well as solvent, as that of another solution.
The process of movement of a substance (solid, liquid or gas) from the region of higher concentration to the region of lower concentration so as to spread uniformly is called diffusion.

What is active transport?
Membrane protein-mediatecl movement of a substance across a membrane against a concentration gradient. It is an energy-requiring process.

Plasma membrane defines the boundary of the cell and regulates the flow of materials into and out of the cell.

See lessWhat would happen if plasma membrane ruptures?
Ruptured plasma membrane generally heals within no time but if rupturing does not heal, the cell contents will spill over and the cell is killed.
