As the basic unit of biological structure and function, cells are dynamic and in constant movement. A large number of proteins, hormones, neurotransmitters and other goods produced in cells need to move between various organelles, and some even have to be transported outside the cells. How a cell organizes its logistics is a complex basic biological problem. Vesicle transport is called the logistics system of cells. because macromolecules and granular substances can not pass directly through the cell membrane, vesicles are produced from one kind of organelle in the way of budding, and then fuse with another kind of cell membrane after disconnection. In this way, vesicles become containers for loading goods.
