• secretory pathway
  30 October 2003

  There are two main classes of traffic intermediates that operate in intracellular trafficking pathways: small round vesicles, and large pleiomorphic carriers (LPCs).
  large pleiomorphic carriers (LPCs)
  While both are essential, the LPCs appear to be responsible for moving the bulk of the secretory traffic between distant compartments.
  LPCs are much larger and more variable in shape than vesicles, and they have evident interconnected tubular and saccular/cisternal components.
  LPCs appear (...)

  Definition: In cell biology, an organelle /ɔːrɡəˈnɛl/ is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.
  Types
  endoplasmic reticulum
  Golgi apparatus
  mitochondria
  peroxysomes
  lysosomes
  Intercellular membrane transport
  Intracellular organelle transport is essential for morphogenesis and functioning of the cell. (...)

• endosomes
  26 January 2005

  An endosome is a membrane-bound compartment inside cells, roughly 300-400 nm in diameter when fully mature (WP).
  Many endocytotic vesicles derived from the plasma membrane are transported to an endosome and fuse with it. Some endocytosed material passes through endosomes on its way to lysosomes.
  Endosomes are, in part, responsible for the sorting of endocytosed material before transport to lysosomes. This allows some material to be returned to the plasma membrane.
