| Term | Definition |
|---|---|
| cell membrane | Protects the inside of a cell from the environment outside of a cell. |
| cell wall | Protects a cell from attack by viruses and other harmful organisms. |
| flagella | That whip back and forth and move a cell. |
| cilia | They can move a cell or move molecules away from a cell. |
| cytoplasm | Contain a cell’s cytoskeleton. |
| cytoskeleton | This framework gives a cell its shape and helps it move. |
| nucleus | DNA is organized into structure called chromosomes. |
| nucleolus | It makes ribosomes, organelles that are involved in the production of proteins. |
| ribosome | They also can be attached to a weblike organelle called the endoplasmic reticulum. |
| rough endoplasmic reticulum | Rough ER is the site of proteins production. |
| smooth endoplasmic reticulum | It makes lipids such as cholesterol. It is important because it helps remove harmful substances from a cell. |
| mitochondria | Energy is released during chemical reactions that occur in the mitochondria. |
| chloroplast | The sugar contains stored chemical energy that can be released when a cell needs it. |
| golgi apparatus | It package the proteins into tiny, membrane-bound, ball-like structures. |
| vesicles | Transport substances from one area of a cell to another area of a cell. |
| lysosome | Contain substances that help break down and recycle cellular components. |
| vacuoles | Organelles that store food, water, and waste material. |
