| Organelle | Structure that performs a specific function within the cell |
| Cytoplasm | The fluid-like substance found inside the cell. Hold the organelles in place. |
| Nucleus | Control center of the cell. Contains two membranes and DNA. Found in Eukaryotic cells. |
| Nucleolus | Small structure found inside the nucleus. Ribosomes are produced here. |
| Endoplasmic Reticulum | ER: acts like a highway system of the cell. |
| Rough ER | Folded membranes that are covered in proteins. |
| Smooth ER | Folded membrane that produces proteins and breaks down toxins. |
| Ribsome | The smallest of organelles. Produces Proteins. Can be attached or free floating. |
| Golgi | Packages and transports materials throughout the cell. |
| Mitochondria | Produces energy (ATP) for the cell. Has two membranes and their own DNA. |
| Cell membrane | Protective barrier found in all cells. |
| Cytoskeleton | Web of proteins that acts like a muscle and skeleton to help support the cell. |
| Chloroplast | Produces food by using sunlight in the process called photosynthesis. Found in plant and algae cells. Has two membranes and their own DNA. |
| Lysosome | Helps to break down food, wastes, and invaders of the cell. Considered to be the trash can or police of the cell. Mostly found in animal cells. |
| Vacuole | Stores water and other digestive enzymes. Helps to support the cell. Found mostly in plant cells. Can act like a lysosome. |
| Cell Wall | Found only in plant cells. The outtermost part of the cell. Helps to protect and support the cell. |
