| What is the nucleolus? | A dense body found within the nucleus, where ribosomes are made |
| What is the rough endoplasmic reticulum? (rER) | A system of interconnected membrane bound, flattened sacs. |
| What are on the rER surface? | Ribosomes |
| What happens to proteins inside the rER? | They assume their three- dimensional shape |
| What structure is the cell surface membrane? | Phospholipid Bilayer |
| What is the smooth endoplasmic reticulum?(sER) | Smooth ER makes lipids and steroids |
| What is the golgi apperatus? | Stacks of flattened sacs, formed by the fusions of vesicles frowm the ER, it modifies proteins and packages them into vesicles for transport |
| What are lysosomes? | Spherical sacs containing digestive enzymes, involved in the breakdowns of unwanted structures in the cell |
| What are mitochondria the site of? | Aerobic Respiration |
| What are centrioles? | Hollow cylinders, they are involved in the formation of the spindle during nulear division |
