What role do transport vesicles play in the endomembrane system?
Understand the Problem
The question is asking about the function of transport vesicles within the endomembrane system of a cell. The endomembrane system is a network of organelles that work together to synthesize, modify, and transport proteins and lipids. Transport vesicles are small, membrane-bound sacs that bud off from one organelle and fuse with another, carrying cargo between them. The question asks us to select the correct role of transport vesicles.
Answer
Transport vesicles move proteins and membranes between organelles in the endomembrane system.
Transport vesicles facilitate the movement of proteins and membranes between different compartments of the endomembrane system. They bud off from one organelle and fuse with another, delivering their contents and integrating the system.

More Information
The endomembrane system includes the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the plasma membrane. Transport vesicles ensure that molecules synthesized in one part of the cell can be transported to another, enabling the cell to function properly.
