vesicle
A vesicle is a small membrane enclosed compartment within a cell, while vacuoles are larger membrane-bound compartments.
Vesicles such as lysosomes, proteasomes, and peroxisomes function in degradation of toxic components (bacteria, damaged or short-lived proteins,metabolites).
Secretory vesicles (exosomes) are formed at the Golgi complex and transported to the cell membrane where they release their contents.
Endosomes may form at the plasma membrane by pinocytosis as clathrin-coated pits, by phagocytosis (phagosomes) or by receptor-mediated endocytosis, and are shuttled back and forth between plasma membrane and nucleus by cytoskeletal transport mechanisms, or may be transported across epithelial cells for release at the opposite membrane (transcytosis).
