Cell Transport & Homeostasis

Front

Facilitated Diffusion

Back

Movement of particles from an area of higher concentration to an area of lower concentration using a protein channel.

Front

Concentration Gradient

Back

The difference in concentration of a substance between two areas, typically measured from high to low concentration.

Front

Active Transport

Back

Movement of particles across a membrane from an area of lower concentration to an area of higher concentration, requiring energy.

Front

Diffusion

Back

The process by which molecules spread from areas of high concentration to areas of low concentration without the need for energy.

Front

Osmosis

Back

The diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

Homeostasis

Back

The ability of a cell or organism to maintain a stable internal environment despite changes in external conditions.

Front

Endocytosis

Back

The process by which a cell engulfs material from its environment, bringing it into the cell.

Front

Exocytosis

Back

The process by which a cell expels materials to the outside environment.

Front

Selectively Permeable Membrane

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

Equilibrium

Back

A state in which the concentration of a substance is equal throughout a space, resulting in no net movement.
