Study of Osmosis

Study of Osmosis :-
Osmosis refers to the movement of one, less concentrated solvent through a semipermeable membrane to another, more concentrated solvent. A semi-permeable membrane is a membrane or barrier that allows some molecules or substances to cross, but not others. The membranes of cells are semi-permeable, too. They allow water and certain solutes, small molecules that are dissolved in a solvent such as water, to cross but other solutes cannot cross. Osmosis plays a critical role in plant and animal cells. It helps in the distribution of nutrients and in the release of waste products.
