- surface lacks ribosomes
5 True/False questions
cytoplasm → a semi fluid, jellylike substance
contractile vacuoles → develops by the coalescence of smaller vacuoles themselves derived from the GA and ER.
plasma membrane → surface has ribosomes
golgi apparatus → proteins are modified stored and sent out
food vacuoles → membrane-bounded vesicles formed by phagocytosis
