Term
| Rough Endoplasmic Reticulum |
|
Definition
| Synthesizes and exports proteins |
|
|
Term
| Smooth Endoplasmic Reticulum |
|
Definition
| Produces lipids, assists in detoxification. Smooth because it lacks ribosomes. |
|
|
Term
|
Definition
| Modifies, sorts, and packages proteins. |
|
|
Term
|
Definition
| Vesicles that bud from the Golgi apparatus. Contain digestive enzymes. The destruction of cells by their own lysosomes is called autolysis. |
|
|
Term
|
Definition
| Vesicles. Similar to lysosomes but contain different enzymes and are not produced by Golgi apparatus. Neutralize free radicals and break down fatty acids. |
|
|
Term
|
Definition
| network of thin tubes and filaments that give the cell its shape |
|
|
Term
|
Definition
| hollow tubes that hold organelles in place, maintain the cell's shape, and guide organelles and molecules as they move within the cell. |
|
|
Term
|
Definition
| Long threads of protein that contribute to cell movement. |
|
|
Term
|
Definition
| Anchor the nucleus and some other organelles to their places in the cell. |
|
|
Term
|
Definition
| Hairlike structures that extend from the cell's surface and assist in movement. |
|
|
Term
|
Definition
| In animal cells- organize the microtubules of the cytoskeleton during cell division. |

Definition
| Only in plant cells. Large, fluid-filled organelle that stores water, enzymes, and metabolic waste. |
|
|
Term
|
Definition
| Only in plant cells- organelles that are surrounded by a double membrane and contain own DNA. |
