Detailed explanation-1: -The movement of water molecule from a region of higher concentration to a region of its lower concentration through a semi permeable membrane is called Osmosis.
Detailed explanation-2: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.
Detailed explanation-3: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Detailed explanation-4: -Diffusion is random movement of molecules but has a net direction toward regions of lower concentration in order to reach an equillibrium. Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane.
Detailed explanation-5: -Diffusion is the net movement of substances from an area of higher concentration to an area of lower concentration. This movement occurs as a result of the random and constant motion characteristic of all molecules, atoms, or ions (due to kinetic energy) and is independent from the motion of other molecules.
