| cell wall | in plants only; provides strength and support; |
| tough and rigid and made of cellulose | cell wall |
| nucleus | brain of the cell - control center |
| nucleolus | produces ribosomes and located in the nucleus |
| nuclear membrane | surrounds the nucleus and has tiny pores |
| ribosomes | smallest organelle; makes proteins |
| most abundant organelle; no membrane | ribosome |
| endoplasmic reticulum (ER) | transportation system |
| smooth ER (endoplasmic reticulum) | without ribosomes |
| rough ER (endoplasmic reticulum) | with ribosomes |
| mitochondria | powerhouse of the cell (makes ATP) |
| where oxygen goes and makes energy | mitochondria |
| golgi bodies (golgi apparatus) | package, change and ship proteins |
| vesicles | membrane covered compartments; pinch off from gogli bodies |
| vacuoles | storage sacs; store food, water, waste |
| central vacuole | largest organelle in plant cells |
| contractile vacuole | pumps out excess water |
