a membrane bound sac that contains materials involved in cellular transport
A
cell
B
flagellum
C
vesicle
D
mitochondria
Explanation: 

Detailed explanation-1: -Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. Other than the fact that vacuoles are somewhat larger than vesicles, there is a very subtle distinction between them: the membranes of vesicles can fuse with either the plasma membrane or other membrane systems within the cell.

Detailed explanation-2: -Vesicles are small membrane bound sacs that transport materials around the cell and to the cell membrane. The vacuoles are like storage centers. Plant cells have larger vacuoles than animal cells.

Detailed explanation-3: -The Golgi apparatus (/ˈɡɒldʒi/), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

Detailed explanation-4: -The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.

Detailed explanation-5: -Transport vesicles Membrane-bound and secreted proteins are made on ribosomes found in the rough endoplasmic reticulum. Most of these proteins mature in the Golgi apparatus before going to their final destination which may be to lysosomes, peroxisomes, or outside of the cell.
