| cell membrane | forms the outside boundary that separates the cell from its environment. Controls what substances come in and out of the cell |
| ribosomes | produce proteins |
| endoplasmic reticulum | passageways in the cell that carry materials from one part of the cell to another, surrounds the nucleus |
| chloroplasts | found only in plant cells. capture energy from sunlight and use it to produce food for the cell. |
| cell wall | a ridgid layer of non-living material that surrounds the cells of plants. |
| mitchondria | The power house of the cell , rod like structure with what looks like squiggly lines in the middle. |
| vacuole | the storage are of the cell. Stores food,water and other materials. |
| nucleus | The brain of the cell. The cells control center directing all the cell's activities. |
| cytoplasm | The region between the cell membrane and the nucleus. Gel-like fluid. |
| Diffusion,osmosis,Active transport | 3 ways in which materials are transported through the cells. |
| Diffusion | movement of gas, food and waste and oxygen through the cell |
| Osmosis | movement of water through the cell. |
| Active transport | movement of materials through the cell membrane using energy. |
