Endoplasmic reticulum

numerous canals that serve in transporting molecules as proteins thru out cytoplasm

ribosomes

synthesize proteins and are located free in the cytoplasm or on the surface of the rough ER

if ER lacks ribosomes on the surface, it is called

smooth ER and doesn't serve as a region of protein synthesis

mitochondria

"Powerhouse" of a cell. possess double membrane and provide the main location for cellular energy production of ATP

lysosomes

membranous sacs that contain intracellular digestive enzymes for destroying debris and worn-out organelles



vesicles
