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.
Intercellular membrane transport
Cellular organelles in the exocytic and endocytic pathways have a distinctive spatial distribution. They communicate through an elaborate system of vesiculo-tubular transport (vesicular transport or vesicle transport).
