define osmosis and write its importance
Answers
Movement of a solvent through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane. More from Merriam-Webster on osmosis.
There are three types of osmotic solutions: Isotonic, Hypotonic, and Hypertonic.
Isotonic: Equal. Water moves in and out of the cell at an equal rate. ...
Hypotonic: "hypo" hippo. Water moves into the cell, making it swell and get fat (like a hippo). ...
Hypertonic: "like a raisin"
The biological importance of osmosis is that it facilitates the distribution of essential nutrients in the body and the excretion of metabolic waste products. Cells have semipermeable membranes, and osmosis makes it possible for liquid solvents to pass through these cell membranes.
