Cell Part and Function
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. |
