AKS 2 Cell Transport

Front

Exocytosis

Back

Process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

Front

Plasmolysis

Back

Contraction of the protoplast of a plant cell as a result of loss of water from the cell.

Front

Active Transport

Back

Movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

Concentration Gradient

Back

Difference in the concentration of a substance between two areas.

Front

Hypotonic

Back

Solution with a lower concentration of solutes compared to another solution.

Front

Hypertonic

Back

Solution with a higher concentration of solutes compared to another solution.

Front

Facilitated Diffusion

Back

Process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.

Front

Osmosis

Back

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

Front

Tonicity

Back

Ability of a solution to cause a cell to gain or lose water.

Front

Passive Transport

Back

Movement of molecules across cell membranes without need of energy input.
