Question

Define osmosis. Explain the different types of osmosis with appropriate examples

Answer 1

Answer:

1. Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
2. Types of osmosis are a) endosmosis b) exosmosis

Answer 2

The process of movement of water from higher concentration to lower concentration through plasma membrane is called osmosis.

For ex.

• if an object is kept in hypertonic solution the cell loses water and shrinks if cell is kept in hypotonic solution the cell swells up.
