| Vesicle | Sac involved in transporting substances in the cell. |
| Lysosome | Digest and recycle large food particles and organelles. |
| Smooth Endoplasmic Reticulum | System of channels formed by folded membrane; highway system; lipids made here. |
| Golgi bodies | Packages proteins for export to other cells; attach carbohydrate and proteins to proteins |
| Nuclear envelope | Membrane that surrounds the nucleus. |
| Cytoplasm | Fluid in cell that surrounds organelles. |
| Vacuole | Sac that stores food or water; large one of these found in plants--maintains structure |
| Plasma membrane | Protects cell; Controls movement of substances in and out of the cell; it's selectively permeable |
| Mitochondria | Release energy from sugar during cellular respiration. |
| Centrioles | Pair of structures that assist the cell in cell division. |
| Nucleus | Directs cellular activities; contains chromosomes. |
| Nucleolus | Assembles ribosomes |
| Chromosomes | Contain genetic information ;made of DNA; found in nucleus. |
| Ribosomes | Site of protein-making (synthesis); located on Rough E.R. or floating in cytoplasm. |
| Rough Endoplasmic Reticulum | System of channels formed by folded membrane; highway system; "dotted with ribosomes". |
| Cell wall | Supports and protects cell; found only in plant cells |
| Cilia | Aid in movement; short |
| Flagella | Aid in movement; long |
| chloroplasts | Use the sun's energy to make sugars during photosynthesis; found only in plants |
| prokaryotic | Type of cell found in bacteria with no true nucleus or other membrane-bound structures. |
| eukaryotic | Type of cell that contain a nucleus and other membrane-bound structures. |
