| Term | Definition |
| active transport | type of movement of particles into or out of the cell that DOES require energy input from the cell |
| Brownian movement | random motion of particles due to the orbit and spin of electrons around the nucleus of all atoms involved |
| diffusion | movement of particles from an area of high concentration to an area of lower concentration; passive transport |
| endocytosis | process of moving large 'chunks' of material into the cell that forms vesicles; active transport |
| equilibrium | condition that is indicated when concentrations are the same inside and outside the cell; water moves in and out at the same rate |
| exocytosis | process of moving large 'chunks' of material out of the cell through the use of vesicles; active transport |
| facilitated diffusion | type of passive transport that requires the presence of carrier molecules or channel proteins to allow diffusion of particles |
| fluid mosaic model | term that is used to describe the consistency and make-up of the plasma membrane of cells |
| hypertonic | water moves out faster than in & the cell shrinks; solution with a higher solute concentration than inside the cell |
| hypotonic | solution with a lower solute concentration than inside the cell; water moves in faster than out & the cell swells |
| isotonic | same concentration inside and outside the cell; is at equilibrium and water moves in and out at the same rate |
| osmosis | type of diffusion that only involves water moving across a semipermeable membrane from high to low concentration |
| passive transport | type of movement of particles in or out of a cell that does NOT require energy input from the cell |
| permease | proteins that allow for specific materials to diffuse into or out of a cell |
| phagocytosis | process of the cell 'eating' solid food particles; type of active transport |
| pinocytosis | process of the cell 'drinking' liquid droplets; type of active transport |
| plasma membrane(s) | another term for 'cell membrane'; is a phospholipid bilayer with embedded proteins |
| plasmolysis | when a plant cell loses too much water, the cell shrinks and its plasma membrane 'breaks away' from the cell wall |
| proton pump | protein complex in the cell membrane that actively moves positive atomic particles across the membrane (low to high) |
| semipermeable | some things are allowed to pass through, while others are not able to cross |
