| A | B |
| 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 |
| vesicle | sac that transports substances |
