| Cell Membrane | The thin layer that surrounds a cell and controls the movements of materials into and out of the cell |
| Cytoplasm | The gel-like are in the cell that holds all of the parts of the cell |
| Cell Wall | Rigid structure around the cell that provides shape and support; found in the cells of plants, algae, fungi, and most bacteria |
| Nucleus | The control center of the cell that contains and protects the DNA |
| Chloroplast | Green, chlorophyll-containing organelle that converts sunlight, carbon dioxide, and water into sugar (food!) |
| Mitochondrion | The powerhouse of the cell, that breaks down sugar into energy |
| Ribosomes | Small round structures that makes the proteins, building blocks |
| Endoplasmic Reticulum | It is the transport system of the cell that moves materials areound the cell |
| Golgi Bodies | This stores and packages the proteins for export out of the cell |
| Vacuoles | Storage place for water, food, and waste inside a cell; plants have one big vacoule, animals have many small ones |
| DNA | Genetic information of life that is stored in the nucleus. (deoxyribonucleic acid) |
| Organelles | The "mini organs" in a eukaryotic cell |
| Cells | Smallest unit of life; All living things are made out of cells |
| Tissue | Groups of cells that work together to do one job. (examples include muscle tissue and skin tissue) |
| Organ | A structure made of different tissues that work together. (examples include the heart, the eye, and the brain) |
| Organ System | A combination of different organs that help do related functions (examples include circulatory system and digestive system) |
