Diagram labels and functions
| Structure / stage | Function |
|---|---|
| Cell membrane | Controls movement into and out of the cell. |
| Cytoplasm | Fluid where many chemical reactions take place. |
| Nucleus | Stores DNA and coordinates cell activity. |
| Mitochondrion | Transfers energy from respiration into ATP. |
| Ribosome | Builds proteins from amino acids. |
| Golgi apparatus | Modifies, sorts and packages proteins. |
A typical human cell
Most human cells have a membrane, cytoplasm, nucleus, mitochondria, ribosomes, ER and Golgi apparatus, but the amounts and shapes vary with function.
Specialized human cells
Neurons extend long axons, muscle fibers pack in contractile proteins, and mature red blood cells lose the nucleus to carry more hemoglobin.
