Front

Diffusion

Back

The process where particles move from an area with a high number of particles to an area with a lower number of particles.

Front

Dynamic Equilibrium

Back

A state in which particles keep moving, but the overall amount stays the same everywhere.

Front

Concentration Gradient

Back

The difference in the amount of a substance between two areas.

Front

Facilitated Diffusion

Back

A type of diffusion where proteins help move substances across the cell membrane without using extra energy.

Front

Osmosis

Back

The movement of water through a special membrane called a selectively permeable membrane.

Front

Isotonic

Back

A condition in which the cell and its surrounding solution have the same concentration of substances.

Front

Hypotonic

Back

A solution with a lower concentration of dissolved substances than inside the cell, causing water to enter the cell.

Front

Hypertonic

Back

A solution with a higher concentration of dissolved substances than inside the cell, causing water to leave the cell.

Front

Active Transport

Back

The process of moving substances from an area of low concentration to an area of high concentration by using energy.

Front

Endocytosis

Back

The process where a cell takes in a large particle by wrapping part of its membrane around it.
