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 |
Cell Theory | Theory that states all living things are composed of cells |
