| cytosol | the gel-like material that fills the cell |
| inclusions | granular stores of compounds |
| ribosomes | site of protein production |
| smooth endplasmic reticulum | no ribosomes |
| rough endoplasmic reticulum | ribosomes |
| golgi apparatus | shipping and recieving center of the cell |
| lysosomes | contain digestive enzymes and acids to break down organic material |
| peroxisomes | contain enzymes that detoxify free radicals of oxygen |
| mitochondria | energy production |
| cytoskeleton | network of protein fibers that form support to cell and anchor organelles |
| microfilaments | Actin. smallest |
| intermediate filaments | kerotin. middle sized |
| microtubules | tubulin. largest |
| plasma membrane | composed of a greasy phospholipid bilayer |
| fluid mosaic model | human cell fused with mouse cell to show that they will mix |
