| cell wall | a rigid structure that surrounds the cell membrane and provides support to the cell |
| ribosomes | the site of protein synthesis (creation) |
| lyosomes | cell organelle filled with enzymes needed to break down certain materials in the cell |
| cytoplasm | a jellylike fluid inside the cell in which organelles are suspended |
| vacuole | cell organelle that stores materials such as water, salts, proteins, and carbohydrates |
| golgi apparatus/body | a system of membranes that modifies and packages proteins for export by the cell |
| endoplasmic reticulum | a cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another |
