Cell In Its Environment

Front 1

selectively permeable

Back 1

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

Front 2

diffusion

Back 2

the process by which molecules move from an area of higher concentration to an area of lower concentration.
-the main method by which small molecules move across the cell membrane.

Front 3

osmosis

Back 3

the diffusion of water molecules through a selectively permeable membrane.

Front 4

active transport

Back 4

the movement of materials through a cell membrane using cellular energy.

Front 5

passive transport

Back 5

the movement of materials through a cell membrane without using energy.
