Endosmosis Examples

Endosmosis is the diffusion of water from the cell exterior to the cell interior or cytoplasm. The study of endosmosis is possible if you keep a cell in the hypotonic solution. In endosmosis, the solute and solvent concentration inside and outside the cell are as follows: High solvent and low solute concentration in the cell …
