| Term | Definition |
|---|---|
| nucleus | where DNA lives, double membrane w/ holes |
| nucleolus | builds ribosomes |
| organelles | specialized structures in cell |
| ribosomes | build proteins for cell |
| RER | build proteins for outside of cell |
| transport vesicles | transport things in cell |
| golgi apparatus | sends transport vesicles where they're supposed to go outside cell |
| SER | helps make lipids, build glucose, detox, stores calcium |
| lysosomes | acid bags. defense/digestion/recycling |
| apoptosis | cell suicide |
| peroxisomes | digest stuff |
| mitochondria | turns food/oxygen into ATP |
| cell membrane | isolates cell from outside, controls what comes in/out |
| cytoplasm | water w/ some dissolved stuff |
| microfilaments | actin/myosin, lets cell change shape. built up/broken down after use |
| intermediate fibers | holds cell together, resists pulling. permanent |
| microtubules | spindles for mitosis/meiosis. cilia in lungs/villi in intestines |
| cell wall | structure, made of cellulose |
| plastids | stores pigments |
| chloroplasts | stores chlorophyll |
| leucoplasts | stores starch |
| chromoplasts | stores carotenoids + stuff |
| central vacuole | stores mostly water, helps give structure |
| plant cells | no lysosomes/peroxisomes |
| animal cells | no cell wall/plastids/central vacuole |
