function of the human cells
| Term | Definition |
|---|---|
| plasma membrane | separates the internal components of the cell from the surrounding environment, essential to the life of the cell |
| cytoplasm | contains many suspended organelles, or cell structures, medium for chemical reactions |
| nucleus | control center of the cell, regulates cell activity, houses genetic material |
| nuclear membrane | protects the nucleus, allowing in only specific materials |
| nucleolus | forms RNA and ribosomes |
| mitochondria | convert nutrients into energy for use by the cell/ body; create adenosine triphosphate (ATP) |
| ribosomes | proteins synthesis for both internal and external use |
| cilia | aid in the movement of substances along the surface of the cell |
| flagella | move the cell itself, through a whip-like motion |
| endoplasmic reticulum | transports material throughout the call |
| rough endoplasmic reticulum | supports the synthesis and transport of proteins, make proteins |
| smooth endoplasmic reticulum | supports the synthesis of some lipid molecules, including steroids, makes lipids |
| Golgi apparatus | packing and shipping plant of the cell . packages and releases materials secreted by the cell for external use. forms lysosomes for sure within the cell |
| lysosomes | digest waste materials including damaged materials found in the cell, old cell components, and materials entering cell |
| cytoskeleton | maintains the shape and structure of the cell. keeps organelles in place and moves them throughout the cell as needed. |
| centrioles | participates in cell reproduction through the distribution of DNA to new cells |
