| Major part of a cell | nucleus and cytoplasm |
| Controls enter and exit of a cell | selectivley premeable |
| Chemical structure of a cell | lipids and protien |
| Plays a role in synthesis of certian types of molecules | ER |
| Refines or packages the protiens which were synthesized by ribosomes associated with the ER | Golgi Apparatus |
| Transmits nerve impulses | nerve cells |
| A mass of fluid surrounding the nucleus | cytoplasm |
| Fibers composed of protien and DNA molecules | Chormatin |
| Elegant fluid sacs that vary in size and shape; move slowly through cytoplasm | Mitochondrion |
| Breaks down molecules of nutrients or foreign particles | Lysosome |
| Located in cytoplasm near G.A. and nucleus | Centrosome |
| Lie at right angles to eachother and function in cell reproduction | Centriole |
| Tiny rods of protien arranged in bundles | Microfiliments |
| Long and slender tubes with diameter 2-3 times bigger than microfiliments | Microtubles |
| Substances that move readily through a cell membrane by diffusion | Sugar and oxygen |
| Molecules become scattered from regions of higher concentration to lower levels of con. | Diffusion |
| Water molecules from lower to higher levels of concentration | Osmosis |
| Water leaves a cell | Hypertonic |
| Water enters a cell | Hypotonic |
| Water and dissolved substances are forced through thin porous walls of blood capillaries | Filtration |
