1. active transport - movement of materials through a membrane against a concentration gradient
2. endocytosis a process by which a cell surrounds and takes in material from it's environment
3. exocytosis is the expulsion or secretion of materials from a cell
4. facilitated diffusion the passive transport of materials across a plasma membrane with the aid of transport proteins
5. hypertonic solution the concentration of dissolved substances outside the cell is higher than the concentration inside the cell
6. hypotonic solution the concentration of the dissolved substances is lower in the solution outside the cell than the concentration onside the cell
7. isotonic solution the concentration of dissolved substances in the solution is the same as the concentration of dissolved substances outside the cell
8. osmosis the diffusion of water across a selectively permeable membrane
9. passive transport movement of particles across a cell membrane by diffusion......
