| prokaryotes | cells that have no nucleus |
| eukaryote | cells that have a nucleus and organelles |
| nucleus | controls the cells activities - brain of the cell |
| nuclear membrane | protects and defines the nucleus |
| chromatin | genetic materials of the cell |
| nucleolus | makes ribosomes |
| cytoplasm | cell substance between nucleus and cell membrane, has consistency of gelly |
| mitichondria | prodoces energy |
| endoplasmic reticulum (ER) | carry proteins and other materials from one part of the cell to another |
| ribosomes | produce proteins and pass it to E.R. |
| golgi bodies | receive proteins from E.R., package them and distribute them to other parts of the cell |
| chloroplasts | Only plant cell have it. Capture energy from sunlight and use it to produce food for the cell. |
| vacuoles | Storage area of the cell |
