216332926organellespecialized structure that performs important cellular functions within a cell
216332927nucleusa part of the cell containing DNA, surrounded by a double membrane
216332928endoplasmic reticulum (ER)an internal membrane system in which components of cell membrane (smooth ER) and some proteins (rough ER) are constructed
216332929Golgi Apparatusa structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell; AKA Golgi Apparatus, Golgi Complex
216332930ribosomeAn organelle that functions in the synthesis of proteins
