| Cytoplasm | matrix in cells; |
| Organelles | Specialized and varies |
| Nucleus | control center; DNA |
| Endoplasmic reticulum | network of membranes; tubular communication; transports molecules |
| Agranular ER | Stores lipids and steroids |
| Granular ER | stores proteins; ribosomes |
| Ribosomes | produces proteins; free or attached |
