Organelles composed of a system of canals, tubes, and sacs that transport molecules inside the cytoplasm are a. Golgi bodies. These are the primary structures for the packaging of cellular secretions for export from the cell. Cell part responsible for maintaining cell shape, internal organization, and cell movements is the a. vesicle.
