Cell Transport

Front

Equilibrium

Back

State that exists when the concentration of a substance is the same throughout a space.

Front

Diffusion

Back

Movement of particles from a region of higher concentration to a region of lower concentration.

Front

Hypertonic Environment

Back

Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell.

Front

Isotonic Environment

Back

Concentrations of water are equal inside and outside the cell.

Front

Types of Cell Transport

Back

Passive and Active.

Front

Passive Transport

Back

Movement of substances across a cell membrane without the use of energy.

Front

Active Transport

Back

Movement of substances across a cell membrane that requires energy.

Front

Osmosis

Back

Movement of water across a selectively permeable membrane from a region of higher concentration to a region of lower concentration.

Front

Facilitated Diffusion

Back

Process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

Concentration Gradient

Back

A difference in the concentration of a substance across a space.
