cellular organelle, subcellular organelle, organite


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.


- 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).
