| prokaryote | simple cell with no organelles | 
| eukaryote | complex cell with organelles | 
| cell membrane | controls what goes in & out of a cell | 
| cytoplasm | fluid inside the cell | 
| nucleus | controls the functions of the cell through DNA | 
| mitochondria | generates energy for the cell to do work | 
| endoplasmic reticulum | transports proteins | 
| Golgi apparatus | packages proteins | 
| ribosomes | make proteins | 
| nucleolus | makes ribosomes | 
| cytoskeleton | provides structure and support for the cell | 
| lysosome | digests wastes & damaged cell parts | 
| vacuole | stores materials for the cell | 
| chloroplast | found in plant cells; produces food | 
| cell wall | found in plant cells; provides support | 
| centrioles | found in animal cells; used during cell division | 
| flagella | used for movement; long & whip-like | 
| cilia | used for movement; many short hairs | 
| Why are cells so small? | more efficient; better surface area to volume ratio |
