| oganelles | tiny cell structures that carry out specific functions within the cell. |
| cell wall | A rigid layer of nonliving materail that surrounds the cells of plants and some other organisms. Protects and supports the cell. |
| cell membrane | Controls what substances come into and out of a cell. |
| cytoplasm | The region between the cell membrane and the nucleus |
| mitochondria | The powerhouse of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions. |
| endoplasmic reticulum | Passageways that carry proteins and other materials from one part of the cell to another. |
| ribosomes | Function as factories to produce proteins. |
| vacuole | The sac within the cytoplasm stores water, food, waste products and other materials. |
| chloroplast | These organelles capture energy from sunlight and use it to produce food for the cell. |
| Golgi body | Receive proteins and other newly formed materials from the indoplasmic reticulum, package them, and distribute them to other parts of the cell. |
| lysosome | Small, round structures containing chemicals that break down certain materials in the cell. |
| nucleolus | found within the nucleus; makes ribosomes |
| nuclear envelope | membrane that surrounds the nucleus and controls what enters and leaves |
| chromatin | found in the nucleus; contains the genetic information (DNA) |
| nucleus | controls all the cell's activities; the "brains"of the cell |
