Question

define the terms istonic, hypertonic ,hypotonic and plasmolysis​

Answer 1

An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side

Hypertonic solution is the one which has higher osmotic concentration and less solvent concentration as compared to another solution.

hypotonic solution is the solution that possess your osmotic concentration and higher solvent concentration as compared to another solution.

Plasmosis - it is a process in which the particle is passed through plasma membrane or cell membrane in cell ......

➝ Isotonic Solution :- If the medium surrounding the cell has exactly the same water concentration as the cell,there will be no net movement of water across the cell membrane.This solution is called an isotonic solution.

• In isotonic solution,water crosses the cell membrane in both directions.However,the amount of water going in is same as the amount of water going out to which there is no overall movement of water.

➝ Hypertonic Solution :- If the medium surrounding the cell has a lower concentration of water than the cell which means that it is a very concentrated solution then the cell will lose water by osmosis.This solution is called hypertonic solution.

➝ Hypotenic solution :- If the medium surrounding the cell has a higher concentration of water than the cell which means that the outside solution is very dilute,the cell will gain water by osmosis.This solution is called hypotonic solution.

➝ Plasmolysis :- Plasmolysis is the detchament of cell membrane of the plant cell from the cell wall when put in hypertonic solution.
