Question

What is osmosis and how many types of osmosis are there ? Explain all its types.

Answer 1

When two solvents of different concentrations are separated by a semi permeable, the moment of solute particles from the region of higher concentration to the region of lower concentration through a semi permeable membrane is called osmosis. The types of osmosis are : hypertonic 
        Hypotonic 
        Isotonic

Answer 2

hypertonic:more solute concentration
hypotonic:less solute concentration
isotonic:same solute concentration
osmosis is a procces in which molecules of solvent pass through semipermeable membrane from lower to higher concentration
