As the basic unit of organism structure and function, cells are dynamic and in constant motion. A large number of "goods" such as proteins, hormones, neurotransmitters, etc. produced in cells need to operate between various organelles, and some even require Transport to the outside of the cell. How a cell organizes its "logistics" is a complex biological problem. Vesicle transportation is called a cell's "logistics system". Because macromolecular and particulate matter cannot pass directly through the cell membrane, So the vesicles are generated from one organelle in the form of budding, and then fused with another organelle membrane. In this way, the vesicles become a "container" for loading goods. This text mainly introduces.
