The endomembrane system is extremely complex for being so miniscule. While there is no one element more important than any other, the vacuoles are an integral part of the system. These mini storage units are the keepers of both nutrients and waste from the entire cell.
The Golgi apparatus is part of the endomembrane system
No. The endomembrane system consists of the endoplasmic reticulum and the Golgi apparatus - i.e things that are formed within the cell. The mitochondria was originally formed from a captured bacterial cell - as it has it's own DNA and its own ribosomes (as well as very bacterial like proteins). It is a separate organelle on its own, although it will have connections with the endomembrane system it is not considered part of it.

vacuole
The vacuole. In the plant cell, there is only one vacuole that is filled with fluid and helps to maintain the shape of the cell. In the animal cell, the vacuole helps with digestion by filling with food and waste material.
The vacuoles.
Its structure is not derived from the ER In contrast to organelles of the endomembrane system, these organelles have at least two membranes separating the innermost space from the cytosol. Their membrane proteins aren't made by the endoplasmic reticulum, but by ribosomes in the cytoplasm and in the organelle itself.
Because they can actually incorporate themselves into the system, the vesicle membrane turns part of the membrane in that location. In the end, they take materials from a part of a cell to another.
the vacuole
The Golgi apparatus or the Golgi complex packages cellular products such as proteins. It is an organelle that is part of the endomembrane system.
