Different kinds of extracellular vesicles produced across diverse eukaryotic kingdoms. (I) Microvesicles are produced directly by pinching off of the plasma membrane. (II) Exosomes are produced through the intermediate structure of multivesicular bodies. (III) Apoptosis results in apoptotic bodies that constitute another type of extracellular vesicle. In plants and fungi, extracellular vesicles must cross a cell wall.
