Types of Solutions on the Basis of Concentration

 

Diffusion : Movement of solutes or ions from higher concentration to lower concentration is called as diffusion. It does not require energy therefore, it is called as passive transport.
Osmosis : The movement of solvent or water from higher concentration
(solvent) to lower concentration (solvent) through a semipermeable
membrane is called as osmosis Or the movement of solvent or water from
lower concentration to higher concentration of solution through a
semipermeable membrane is called as osmosis.
Osmosis can also be called as ‘Diffusion of solvents’.
Endomosis : Movement of solvent into the cell is called as Endomosis.
Exosmosis : Movement of solvent outside the cell is called as Exomosis.

Types of Solutions on the Basis of Concentration

Isotonic Solution : When the concentration of the solution
outside the cell is equal to the concentration of cytoplasm of the
cell, it is called as isotonic solution.
Hypertonic Solution : When the concentration of the solution
outside the cell is more than the inside the cell. Due to this, cell
looses water and becomes plasmolysed.
Hypotonic Solution : When the concentration of the solution
outside the cell is lesser than that of cytoplasm of cell. Due to
this, cell swells up and bursts.

 

Cell Wall
• It is the outermost covering of the plant cells.
• It is absent in animal cells.
• Cell wall is rigid, strong, thick, porous and non-living structure. It is
made up of cellulose and hemicelluloses. Cell walls of two adjacent cells
are joined by a layer called middle lamellae.

Functions of Cell Wall :
(a)It provides definite shape to the cell.
(b)It provides strength to the cell.
(c)It is permeable and allows entry of molecules of different sizes.
(d)It has the characteristics of repair and regeneration.
