| cell membrane | Holds the inner parts of the cell together. A protective barrier that surrounds the cell. |
| cell wall | A rigid structure that surrounds the cell membrane and provides support to the plant cell. |
| chloroplast | This is where photosynthesis takes place. Contains chlorophyll which allows plant cells to make their own food. |
| cytoplasm | A watery gel that supports the cell’s other parts, called organelles. |
| endoplasmic reticulum | Web of tubes and pouches that extend throughout the cell. Acts as a delivery system for materials to travel throughout the cell. |
| mitochondria | Converts the energy in food into a form a cell can use to grow, divide, and do its work. |
| nucleus | Cell’s command center. It contains DNA. It controls all of the cell’s activities. |
| ribosome | Makes proteins for the cells. Proteins are needed for cell growth and repair. |
| vacuole | Like tiny storage tanks, holding and releasing materials that the cell needs. |
| lysosome | This part contains digestive enzymes that destroy worn out or damaged organelles, wastes and invading particles. |
| prokaryote | a single celled organism that does not have a nucleus. Example: Bacteria and Archea |
| eukaryote | An organism made up of cells that have a nucleus. Example: Animals and Plants |
| unicellular | An organism made up of one cell. |
| multicellular | An organism made up of more than one cell |
