Fichas del conjunto (8)
- 1Passive TransportMovement of substances through a cell membrane DOES NOT require energy (diffusion and osmosis)
- 2Selectively PermeableA property of cell membranes that allows some substances to pass through, while others cannot.
- 3HomeostasisProcess by which organisms maintain a relatively stable internal environment.
- 4OsmosisDiffusion of WATER molecules through a semipermeable membrane from HIGH to concentration to LOW concentration
- 5Cell membrane-AKA Plasma membrane
-A flexible boundary that controls the movement of substances into and out of the cell. - 6DiffusionMovement of molecules from an area of HIGH concentration to an area of LOW concentration.
- 7Active TransportMovement of substances through the cell membrane that REQUIRES ENERGY. Move things from an area of LOW concentration to an area of HIGH concentration.
- 8Facilitated DIffusionMovement of molecules from an area of HIGH concentration to an area of LOW concentration with the help of proteins.
