| Cell membrane | The protective covering around all cells, regulates interaction between cell and the environment |
| Cytoplasm | The gelatin like material inside every cell |
| Nucleus | Directs all cell activities and is separated from the cytoplasm by a membrane |
| Ribosome | Organelle that makes proteins , not membrane bound, can be attached or float freely in the cytoplasm |
| Endoplasmic Reticulum | Folded membranes that process and move materials around inside of cell, can be smooth or rough |

| Tissue | A group of similar cells that work together to do one job |
| Organ | A structure made up of two or more different types of tissues that work together |
| Golgi body | Stacked and flattened membrane that sort proteins and other cellular substances and package them into membrane-bound structures called vesicles |
| Unicellular | Organism with one cell |
| Multicellular | Organism having many cells |
| Fermentation | Process when cells do not have enough oxygen for respiration |
| Respiration | Process in which chemical reactions occur that break down food molecules into simpler substances and release their stored energy |
| Photosynthesis | Process of using light energy to make sugars, which can be used as food in plant cells |
| Prokaryotic Cell | Cells without membrane-bound organelles |
| Eukaryotic Cell | Cells with membrane-bound organelles |
