Golgi body | Flattened sacs that modify, package, and transport materials. |
Lysosome | Small organelles that help break down larger food molecules into smaller ones. |
Cell Wall | Outer layer of plant cells; it supports and protects the cell. |

Cell | The basic unit of structure and function in living things. |
Organelle | A tiny cell structure that carries out specific functions in a cell. |
