| A | B |
|---|
| Cell Membrane | Surrounds the cell; regulates what enters and leaves the cell. |
| Cytoplasm | Fluid that fills the cell; site of many chemical reactions. |
| Nucleus | Found within the cytoplasm; controls the functions of the cell (“control center”). |
| Nuclear Envelope | Porous membrane that separates the nucleus from the rest of the cell. |
| Nucleolus | Found within the nucleus; creates ribosomes. |
| Chromosomes | Found within the nucleus; packages of DNA. |
| Ribosome | Found within the cytoplasm and on the Endoplasmic Reticulum; produces proteins. |
| Endoplasmic Reticulum (ER) | Found within cytoplasm; builds and transports lipid and proteins. |
| Rough Endoplasmic Reticulum | Has ribosomes on its surface; assembles and transports proteins. |
| Smooth Endoplasmic Reticulum | Lacks ribosomes on its surface; assembles and transports lipids. |
| Golgi Apparatus | Found within the cytoplasm; modifies and packages proteins and lipids |
| Mitochondria | Found within the cytoplasm; provides energy for the cell (site of respiration). |
| Vesicle | Found within the cytoplasm; membrane-bound storage containers. |
| Lysosome | Found within cytoplasm; special vesicle that contain digestive enzymes (breaks down food and waste within the cell). |
| Centriole | Found within the cytoplasm of animal cells; aids with cell division (controls spindle fibers) |
| Cytoskeleton | Found within the cytoplasm of animal cells; provides internal support for the cell. |
| Cell Wall | Surrounds the outside of the cell membrane of plant cells; provides external support for the cell. |
| Vacuole | Found within the cytoplasm of plant cells; large membrane-bound water storage container. |
| Chloroplasts | Found within the cytoplasm of plant cells; produces carbohydrates (site of photosynthesis). |
