What are the structures responsible for cell transport?

There are three bodies responsible for transport in the cell including the endoplasmic reticulum, the vesicles and the cell membrane. The endoplasmic reticulum moves materials within the cell body, while the vesicles move proteins to the cell membrane, and the membrane transports materials in and out of the cell.

While the endoplasmic reticulum's primary function is transportation, vesicles are also responsible for storing and moving proteins created in the Golgi body to the cell membrane. The cell membrane transports materials into and out of the cell both actively and passively. For example, water is passively transported into the cell by the cell membrane.
