| Term | Definition |
|---|---|
| Cell Membrane | The thin layer of protein and fat that surrounds a cell. It allows some substances to pass through and blocks others. |
| Cytoplasm | Jellylike material located outside the cell nucleus that holds the organelles. |
| Golgi Body | Organelle that changes, processes, and packages proteins, lipids, and carbohydrates into vesicles for export from the cell. |
| Lysosome | Vesicles where the digestion of cell nutrients takes place. |
| Mitochondrion | This organelle converts the energy stored in glucose into a high energy molecule for use by the cell. |
| Nuclear Membrane | The membrane that surrounds the nucleus. |
| Nucleus | It contains mostly DNA in chromosomes and controls many of the functions of the cell by controlling protein synthesis. |
| Nucleolus | An organelle within the nucleus the produces Ribosomal RNA. The RNA is exported into the cytoplasm and forms ribosomes. |
| Ribosome | Small organelles composed of RNA. The synthesize protein. |
| Rough Endoplasmic Reticulum | This ER is covered with ribosomes that give it a rough appearance. Rough ER transport materials, moving proteins and lipids to the Golgi body. |
| Smooth Endoplasmic Reticulum | This ER buds off from the rough ER. It produces lipids and proteins and moves them to the Golgi body for further processing. |
| Vacuole | Fluid-Filled, Membrane-Surrounded Cavities inside a cell. It fills with food being digested and waste material that is on its way out of the cell. |
