Examples of simple diffusion in organism
1) Gas exchange in the alveoli ,during cellular respiration and during photosynthesis 2) Diffusion of fatty acids and fat -soluble vitamins from the villus of the small intestine
Examples of osmosis in organism
1) Absorption of water by root hairs of plants 2) Movement of water from one cell to the adjacent cell 3) Absorption of water at the wall of colon
Examples of facilitated diffusion in organism
1) Movement of glucose across the plasma membrane into the blood vessels 2) Movement of amino acids across the plasma membrane into the cell
Isotonic solution
The concentration of solute in the external solution is equal to the concentration of solute in the cell
Hypotonic solution
The concentration of the solute in the external solution is less than the concentration of the solute in the cell
Hypertonic solution
The concentration of solute in the external solution is higher than the concentration of solute in the cell
The effect of hypotonic solution to the plant cell and animal cell
Plant cell: becomes turgid Animal cell: undergoes hemolysis
The effect of hypertonic solution to the plant cell and animal cell
Plant cell: undergoes plasmolysis and becomes flaccid Animal cell: undergoes crenation
The effect of isotonic solution to the plant cell and animal cell
The size and shape of the cell remains the same
Passive transport in organisms occurs during (1)
