| Term | Definition |
|---|
| ribosomes | Tiny spherical bodies composed of RNA and proteins |
| ribosomes | Actual sites of protein synthesis |
| ribosomes | Floating free or attached to a membranous structure the (rough ER) in the cytoplasm |
| endoplasmic reticulum (ER) | Membranous system of tubules that extends throughout the cytoplasm |
| rough ER | Studded with ribosomes tubules |
| smooth ER | Synthesizes phospholipids and cholesterol |
| smooth ER | Site of steroid and lipid synthesis |
| smooth ER | Lipid metabolism |
| smooth ER | drug detoxification |
| golgi apparatus | Stack of flattened sacs with bulbous ends and associated small vesicles |
| golgi apparatus | Plays a role in packaging proteins |
| golgi apparatus | Packages substances for export from the cell or incorporated into the plasma membrane |
| golgi apparatus | Packages lysosomal enzymes |
| lysosomes | Membranous sacs containing digestive enzymes (acid hydrolases) |
| lysosomes | Digest worn out cell organelles and foreign substances that enter the cell |
| lysosomes | Have the capacity of total cell destruction if ruptured |
| peroxisomes | Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals |
| mitochondria | Rod shaped bodies with a double membrane wall |
| mitochondria | Inner membrane is thrown into folds, or cristae |
| mitochondria | Contain enzymes that oxidize foodstuffs to produce cellular energy (ATP) |
| mitochondria | Referred as the "powerhouses of cell" |
| centrioles | Paired, cylindrical bodies lie at right angles to each other |
| centrioles | Direct the formation of the mitotic spindle during division |
| centrioles | Form the bases of cilia and flagella |
| microfiliaments | Formed largely of actin |
| microfiliaments | A contractile protein |
| microfiliaments | Important in cell mobility (particularly in muscle cells) |
| microtubles | Form the internal structure of the centrioles |
| microtubles | Help determine cell shape |
| rough ER | Provide an area for storage and transport of the ribosomes to other cell areas |
