| concentration | the mass of solute in a given volume of solution, or mass/volume |
| diffusion | the process in which cells in a solution move from an area that is more concentrated to an area where the solution is less concentrated., process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated |
| equilibrium | When the concentration of a solute is the same throughout a solution |
| osmosis | the diffusion of water through a selectively permeable membrane |
| isotonic | means "same strength", when the concentration of two solutions is the same |
| hypertonic | above strength when comparing two solutions it has a greater concentration of solutes |
| hypotonic | below strength when comparing two solutions, the solution with the lesser concentration of solutes |
| facilitated diffusion | the process in which cells in a solution move from an area that is more concentrated to an area where the solution is less concentrated using protein channels, passive transport of materials across a plasma membrane by transport proteins embedded in the plasma membrane |
| active transport | energy-requiring process that moves material across a cell membrane against a concentration difference, the movement of materials through a cell membrane using energy |
| endocytosis | the process of taking material into the cell by means of infoldings, or pockets, of the cell membrane, the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell |
| exocytosis | when the membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell., the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out |
