The vesicles which are formed from rER first transports the proteins to the Golgi apparatus, fusing with the membranes of this organelle. The proteins are then processed as they pass through the Golgi Apparatus. The vesicles then bud off the Golgi apparatus and fuse with the plasma membrane after moving through the cytoplasm. The contents are the vesicles can be released to the outside of the cell in a process known as exocytosis.
Cells also use vesicles to transport other cell products besides proteins. Examples include hormones and digestive enzymes.
This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.
The Golgi complex packs proteins and other materials into membrane-bound vesicles called transport vesicles. These vesicles transport the proteins to different parts of the cell or to the cell membrane for release outside the cell.
Vesicles that transport materials out of the cell are formed at the Golgi apparatus in a process called exocytosis. The vesicles contain the materials to be transported and fuse with the cell membrane to release them outside the cell.
The intake of small membrane vesicles from the extracellular fluid is called endocytosis. This process involves the engulfment of substances by the cell membrane to form vesicles that are then internalized into the cell.

Exocytosis
The Golgi packages materials into vesicles for transport or export from the cell. These vesicles can fuse with the cell membrane to release their contents outside the cell or to other cellular compartments.
The Golgi complex packs proteins and other materials into membrane-bound sacs called vesicles. These vesicles can then transport the packaged materials to different parts of the cell or outside of the cell.
Vesicular transport is an active process in which materials move into or out of the cell enclosed as vesicles. Vesicles are bubble-like structures surrounded by a membrane. They can form at the cell membrane or can fuse with the membrane. Solid particles, droplets of fluid or many molecules at a time can be moved across the membrane in vesicles. Vesicular transport is also known as bulk transport because large quantities of materials can be transported in this way. Th ere are two basic types of vesicular transport-endocytosis and exocytosis.
Osmosis, diffusion, and facilitated diffusion are all opposites of active transport.
Vesicles transport materials in the cell. A vesicle is a small membrane enclosed sack that can have specialized functions depending on what materials they contain.
The transport of molecules from inside a cell to the outside is called exocytosis. In this process, vesicles containing the molecules fuse with the cell membrane, releasing the contents to the extracellular space.
The membrane-bound sacs in the Golgi complex are called vesicles. These vesicles transport and package proteins and other materials synthesized within the cell for storage or secretion.
