Cell Transport Mechanisms

Front

Selectively Permeable

Back

A property of cell membranes that allows some substances to pass through, while others cannot.

Front

Passive Transport

Back

The movement of substances across a cell membrane without the use of energy by the cell.

Front

Diffusion

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

Osmosis

Back

The diffusion of water through a selectively permeable membrane.

Front

Active Transport

Back

The movement of materials through a cell membrane using energy.

Front

Endocytosis

Back

The process by which a cell takes in materials by engulfing them in a vesicle.

Front

Exocytosis

Back

The process by which a cell releases large amounts of material.
