Define osmosis.
With simple words!!

Dear student,
Please find below the answer:

Osmosis is a type of diffusion. Osmosis is the phenomenon when the two solutions having different osmotic concentrations are separated by a semi-permeable membrane and the movement of solvent takes place from a region of low concentration of the solute to a region where there is a high concentration of the solute or from a region where there is a high concentration of solvent to a region where there is a low concentration of solvent.

Hope this clears your doubt.
Regards.
