Describe : Osmosis

Explanation

Definition : Two solutions having unequal concentration are when separated with semi-permeable membrane at that time (solvent) water diffuses from lower concentration to higher concentration. This is called osmosis.

This process is continued till the concentration of both the solutions does not become equal.
Characteristic of a plant cell:
The plant cell is surrounded by a cell membrane and a cell wall.
Hence cell wall is not a barrier to movement.
In the plant cells a vacuolar sap, contribute to the solute potential of the cell.
In plant cells, the cell membrane and the membrane of the vacuole, the tonoplast together are important determinants of movement of molecules in or out of the cell.
Osmosis is the term used to refer specifically to the diffusion of water across a differentially or semi-permeable membrane.
Osmosis occurs spontaneously in response to a driving force.
The net direction and rate of osmosis depend on both the pressure gradient and concentration gradient.
Water will move from its region of higher chemical potential (or concentration) to its region of lower chemical potential until equilibrium is reached.
At equilibrium the two chambers should have the same water potential.
