Nucleus - Control center of the cell. Contains DNA in the form of genes. Rough Endoplasmic Reticulum - System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm Smooth Endoplasmic Reticulum - An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down. Mitochondria - An organelle found in large numbers in most ...
