| cytoskeleton | Helps maintain shape |
| nucleus | "Brain" or control center |
| nucleolus | helps in production of ribosomes |
| smooth endoplasmic reticulum | produces lipids |
| rough endoplasmic reticulum | helps in production of proteins. Has ribosomes attached |
| cell membrane | regulates what enters and leaves |
| centrioles | help in cell division |
