---|---|
Plasma membrane | Outermost limit of cell; selectively permeable; bilayer of phospholipids, proteins, carbs |
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 |
Golgi Apparatus | Refine and package |
