| Term | Definition |
| Nucleolus | Dense, solid structure involved in ribosome synthesis. |
| Smooth endoplasmic reticulum | Used for internal transport of materials. Involved in lipid production, drug detoxification, storage of calcium ions, and aid in glucose release. |
| Chromatin | Strands of DNA when it is not in the dividing process. |
| Free Ribosome | Carries out protein synthesis for proteins to be used inside the cell. |
| Bound Ribosome | Attached to the surface of the rough endoplasmic reticulum. Produces proteins that exit the cell. |
| Rough endoplasmic reticulum | Intracellular transport of proteins to the golgi apparatus. Has ribosomes on the exterior of its channels. |
| Lysosome | Sac bound by a single membrane which contains hydrolitic enzymes used for the destruction of harmful chemicals in the cell. |
| Plasma Membrane | Seperates the interior of the cell from the outside environment and regulates what enters and exits the cell. |
| Mitochondrion | Organelle with a double membrane that changes chemical molecules that the cell cannot use directly into ATP via a process called cellular respiration |
| Golgi Apparatus | Consisting of cisternae, which look like flattened sacs, it collects, packages, modifies and distributes proteins. Products are recieved from the endoplasmic reticulum on the cis side and discharged in vesicles on the trans side, after which they are brought to wherever they are needed in or outside the cell. |
| Nuclear Pore | Hole in the nuclear membrane allowing communication with the rest of the cell. |
| Nuclear Membrane | Isolates the DNA, thus allowing it to carry out its function without being disturbed by other processes in the cell. |
| Nucleus | Controls cells activities, mitosis, replication of DNA, and transcription of DNA. |
| Centrioles | Composed of microtubules, they are associated with nuclear division. |
