| cell | basic unit of life |
| cell membrane | composed of a phospholipid bilayer, controls what enters and leaves the cell |
| active transport | the process by which cells use energy to transport molecules through the cell membrane from areas of low concentration to areas of high concentration |
| diffusion | the movement of molecules from areas of high concentration to areas of low concentration |
| homeostasis | The ability of an organism to maintain a stable internal environment even when the external environment changes |
| phospholipd | a lipid that has a phosphate group replacing one of the fatty acids |
| lipid bilayer | the type of arrangement of molecules that make up the cell membrane |
| nucleus | control center of the cell |
| prokaryote | a cell that doesn't have a nucleus such as bacteria |
