Cell,  | The basic unit of all forms of life |
| Cell Theory | All living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells |
| Cell Membrane | A thin flexible barrier around the cell |
| Cell Wall | A strong layer around the cell membrane |
| Nucleus | A large structure that contains cells genetic material |
| Cytoplasm | The material inside the cell membrane (not including the nucleus) |
| Prokaryotes | Have cell membranes and cytoplasm, but do not contain nuclei |
| Eukaryotes | Cells that contain nuclei |
| Organelles | Specialized structures within the cell that perform important cellular functions |
| Chromatin | The granular material visible within the nucleus, consisting of DNA bound to protein |
| Chromosomes | Chromatin in its condensed form |
| Nucleolus | A small dense region within the nucleus where ribosome assembly begins |
| Nuclear Envelope | A double membrane layer that surrounds the nucleus, allowing material to move into and out of the nucleus |
| Microtubules | Hollow tubes of protein that maintain cell shape |
| Microfilaments | Long thin fibers in the movement and support of the cell |
| Ribosome | A small particle made up of RNA and protein that produce proteins following coded instructions that come from the nucleus |
| Endoplasmic Reticulum | An internal membrane system in which components of the cell membrane are assembled and some proteins are modified |
| Golgi Apparatus | Stacked rough endoplasmic reticulums that attach carbohydrates to proteins. From here, proteins are sent to their final destinations |
| Lysosome | Small organelles filled with enzymes that break down (digest) lipids, carbohydrates and proteins from food into particles that can be used by the cell |
| Vacuole | A sac-like structure which stores water, salts, proteins and carbohydrates for the cell |
| Chloroplast | Use the energy from the sunlight to make energy-rich food molecules in a process known as photosynthesis |
| Mitochondria | Organelles that release energy from stored food molecules, use energy from food to make high-energy compounds (e.g. ATP) |
