WebOsmosis can be defined as the passive movement of water from a higher concentration to a lower concentration through a semi permeable membrane. Tonicity is how capable is a solution to change the size of the cell that is placed in it. Based on this measure, osmosis is divided into three groups: hypotonic, isotonic and hypertonic. A red blood cell. WebDiffusion, osmosis, and tonicity. Movement Across Membranes (videos - Active and passive transport & osmosis ): 1 - Passive processes - require no expenditure of energy by a cell: Simple diffusion = net movement of a substance from an area of high concentration to an area of low concentration (check this animation - How diffusion works ). deviantart punch out bear hugger

The movement of molecules through a cell membrane is termed osmosis or diffusion. Such movement is principally possible because nutritive molecules are smaller than membrane micro pores. If the molecules are too large, no molecular transfer, or diffusion occurs.
