Endomembrane system

As the totality of the endomembrane membrane- cell compartments is referred which are interconnected by vesicle. It is composed of the endoplasmic reticulum ( rough and smooth ), the Golgi apparatus, the plasma membrane, the outer nuclear envelope and the perinuclear space, endosomes, vacuoles, lysosomes and transport vesicles. Also, peroxisomes were identified in 2009 as part of the endomembrane system. In contrast, mitochondria and plastids are not part of the endomembrane system.

The lumen of all these organelles is called exoplasmatisch, ie everything is enclosed by these membranes can come out of the cell without a membrane to pass.
