| Prokaryotic Cell | lack internal membrane-bound structures (organelles) |
| Eukaryotic Cell | have membran-bound structures |
| nucleus | control center of the cell; contains hereditary material |
| organelles | small structures found within the cell which carry out life processes; tiny organs of the cell |
| cell wall | found only in plant cells helps to maintain the shape of the cell; made of cellulose |
| cell membrane | found in both plant and animal cells; separates the cell from the environment; selectively permeable |
| selectively permeable | cell membrane is selectively permeable; it allows some things to enter and keeps other things out; helps to maintain homeostasis |
| nucleoli (nucleolus) | found in the nucleus; produce ribosomes |
| chromosomes | colored bodies; contain the DNA |
| cytoplasm | jelly-like substance found within the cell; holds the organelles; many chemical reactions in the cell take place in the cytoplasm |
| endoplasmic reticulum (ER) | channels for transport within the cell; 2 types smooth and rough (have ribosomes) |
| Ribosomes | site of protein synthesis |
| Golgi Bodies | serve as processing, packaging and storage centers for the products released from the cell |
| lysosomes | sacs that contain strong hydrolytic enzymes; found in most animal cells |
