Endomembrane system1

The endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell. These membranes divide the cell into functional and structural compartments, or organelles. In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane. The system is defined more accurately as the set of membranes that form a single functional and developmental unit, either being connected directlpit, or exchanging material through vesicle transport.[1] Importantly, the endomembrane system does not include the membranes of mitochondria or chloroplasts.

The nuclear membrane contains two lipid bilayers that encompass the contents of the nucleus.[2] The endoplasmic reticulum (ER) is a synthesis and transport organelle that branches into the cytoplasm in plant and animal cells.[3] The Golgi apparatus is a series of multiple compartments where molecules are packaged for delivery to other cell components or for secretion from the cell.[4] Vacuoles, which are found in both plant and animal cells (though much bigger in plant cells), are responsible for maintaining the shape and structure of the cell as well as storing waste products.[5] A vesicle is a relatively small, membrane-enclosed sac that stores or transports substances.[6] The cell membrane, is a protective barrier that regulates what enters and leaves the cell.[7] There is also an organelle known as the Spitzenkörper that is only found in fungi, and is connected with hyphal tip growth.[8]
