Covered by a membrane. Nucleolus Produces ribosomes necessary for translation of genetic information into proteins Nissl Bodies Groups of ribosomes used for protein synthesis. Endoplasmic reticulum (ER) System of tubes for transport of materials within cytoplasm. Can have ribosomes (rough ER) or no ribosomes (smooth ER). With ribosomes, the ER is important for protein synthesis. Golgi Apparatus Membrane-bound structure important in packaging peptides and proteins (including neurotransmitters) into vesicles. Microfilaments/Neurotubules System of transport for materials within a neuron and may be used for structural support....
