Active transport:The movement of a substance across a membrane from a region of its lower concentration to a region of its higher concentration against a concentration gradient, using energy.
Diffusion:The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.
Osmosis:Diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.
Facilitated Diffusion:Transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration by means of a carrier molecule. Since the substances move along the direction of their concentration gradients, energy is not required.
Hypertonic solution:A solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared.
Endocytosis:A process in which cell takes in materials from the outside by engulfing and fusing them with its plasma membrane.
