CELLS

7. Small structure made of microtubes; part of the centrosome
8. Membrane enclosed channels continuous with the nuclear membrane(found next to nucleus); rough & smooth
10. Manufacture proteins; has free & fixed
11. "tail" on a sperm cell allows the entire cell to "swim"
12. Hair-like structures on the surface of cells, "waft" material/debris across their surface

1. Separates the cell from its environment; controls what can enter/exit
2. Stacked,flattened,membranous sacs; modifies and packages secretions such as hormones & enzymes
3. Similar to lysosomes but smaller; contains enzymes and detoxify harmful substances
4. Provides energy for the cell in the form of ATP
5. Spherical vesicles that contain digestive enzymes; formed by Golgi apparatus
6. Contains genetic material(DNA); controls metabolic activity
9. Cell extensions that increase surface area, found in epithelial cells of intestines
