Organelle

|
In cell biology, an organelle is one of several structures with specialized functions, suspended in the cytoplasm of a eukaryotic cell. Organelles were historically identified through the use of some form of microscopy and were also identified through the use of cell fractionation.
A few large organelles probably originated from endosymbiont bacteria:
Other organelles include:
- centriole
- endoplasmic reticulum
- golgi apparatus
- lysosome
- myofibril
- plastids
- nucleus
- peroxisome
- ribosome
- vacuole
- vesicle
- melanosome
- cilium/flagellum
