| endosymbiosis | the condition in which one organism lives inside the cell of another organisms for the benefit of both |
| diffusion | the movement of material from an area of high concentration to low concentration without the use of energy |
| concentration gradient | the difference in concentration between a region of high concentration and a region of low concentration |
| faciliated diffusion | some substances diffuse across the cell membrane more rapidly because of specialized transport proteins in the cell membrane |
| osmosis | the movement of WATER from an area of high concentration to an area of low concentration without the use of energy |
| isotonic solution | a solution that has the SAME concentration of dissolved substances as the living cell placed in it |
| hypotonic solution | contains a LOWER concentration of dissolved substances as the living cell placed in it |
| hypertonic solution | ontains a LOWER concentration of dissolved substances as the living cell placed in it |
| passive transport | transport from an area of high concentration to an area of low concentration without the use of energy |
| active transport | transport from an area of low concentration to an area of high concentration with the use of energy |
| pinocytosis | pinching in of the cell membrane to take in liquids |
| phagocytosis | engulfing solid particles to take into the cell |
