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.
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).
Pathology

- mitochondrial diseases
