| A | B |
|---|
| nucleus | Control center of the cell; stores chromosomes |
| nucleolus | stores RNA and manufactures ribosomes within the nucleus |
| chromatin | Stores genetic information; makes up chromosomes |
| mitochondria | The sites of cellular respiration |
| ribosomes | Where proteins are made |
| rough endoplasmic reticulum | transports proteins (polypeptides) through the cell to the Golgi complex |
| Golgi complex | Process, packages, and delivers proteins out of the cell |
| lysosome | Contains enzymes to digest almost everything in the cell |
| cell membrane | Controls what moves in and out of the cell |
| vacuole | Stores wastes, water, food; creates turgor in plant cells |
| centrioles | Microtubule organizers that help to form the spindle for cell division |
| smooth endoplasmic reticulum | Transports and stores lipids and calcium ions |
| cell wall | Adds support and protection to plant cells and most bacteria |
| chloroplasts | Where photosynthesis occurs to make food for plants |
| cytoskeleton | Internal framework that gives shape to cells and supports the organelles |
| cristae | Inner membranes of mitochondria that increase surface area for greater ATP production |
| turgor | Internal water pressure in central vacuole; gives plants rigidity |
| cilia | Hairlike extensions that enable some cells to move |
| flagellum | Long whiplike extension that enables some cells to move |
| cytosol | The material inside the cell around the nucleus |
| peroxisomes | Contain enzymes to neutralize free radicals; break down fatty acids |
| chromoplasts | Store pigments other than chlorophyll in plant cells |
