Diffusion is the movement of particles from a region of high concentration to a region of low concentration down diffusion gradient.
Diffusion takes place when molecules from high concentration region moves to low concentration region without using added energy.

Diffusion is the movement of particles from a region of high concentration to a region of low concentration down diffusion gradient.
Diffusion takes place when molecules from high concentration region moves to low concentration region without using added energy.
Isotonic - a solution in which the solute and solvent are equally distributed
Hypotonic -a solution which contains more solvent than solute (example: salt solution)
Hypertonic -a solution which contains more solute than solvent (example: sports drink)

Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane.
Osmosis takes place when water molecules from high concentration region moves to low concentration region passing through a semi permeable membrane.

Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane.
Osmosis takes place when water molecules from high concentration region moves to low concentration region passing through a semi permeable membrane.
OsMoSiS
DEFINITION
HOW?
A semi permeable membrane allows some molecules to pass through it and prevents other large molecules from crossing through it.
