Biology - Ch. 8 active transport -energy-expending process by which cells transport materials across the cell membrane against a concentration gradient endocytosis- active transport process where a cell engulfs materials with a portion of the cell's plasma membrane and releases the contents inside of the cell exocytosis -active transport process by which materials are secreted or expelled from a cell facilitated diffusion -passive transport of materials across a plasma membrane by transport proteins embedded in the plasma membrane hypertonic solution- in cells, solution in which the concentration of dissolved substances outside the cell is higher than the concentration inside the cell; causes a cell to shrink as water leaves the cell hypotonic solution- in cells, solution in which the concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell; causes a cell to swell and possibly burst as water enters the cell
