| A | B |
| Cell | Building block of life |
| Cell membrane | regulates what enters and exits a cell |
| Cytoplasm | Colloid with organelles |
| Nucleus | contains chromosomes |
| Nuclear membrane | regulates what enters and exits nucleus |
| chromosomes | made of DNA and protein |
| DNA | genetic material with "code of life" |
| organelles | membrane bounded structures in cytoplasm |
| ribosomes | in cytoplasm and produce protein |
| golgi bodies | organelle that wraps protein |
| endoplasmic reticulum | move materials within the cell |
| lysosomes or "suicide sacs" | breakdown dead cells |
| cell wall | plant cell structure for support |
| chloroplasts | In plant cell only & for photosynthesis |
| prokaryotic cells | bacterial cells - lack nuclleus and organelles |
| eukaryotic cells | have nucleus and organelles |
| microtubules | protein scaffolding |
| hierarchy of organization | cells-->tissues-->organ-->system |
| centriole | produce fibers for cell division |
