Most eukaryotic cells also contain other membrane - bound organelles such as mitochondria, chloroplasts and the Golgi apparatus.

It is probable that most other membrane - bound organelles are ultimately derived from such vesicles.

Eukaryotic cells also contain many internal membrane - bound structures called organelles.

Autophagy (more specifically macroautophagy) is the process by which cellular compartments, such as membranes and organelles and also protein aggregates, are recycled back into their building blocks [122].

Endosomes are the main organelles for sorting material that has been taken up from the exterior of the cell by the plasma membrane (endocytosis).

Vesicle is a collective term for a number of different, small membrane - bound organelles.

With Cell Painting, a technique developed at the Broad, researchers tag eight cellular components and organelles (actin, cytoplasmic RNA, endoplasmic reticulum, Golgi apparatus, mitochondria, nucleus, nucleolus, and the plasma membrane) with fluorescent dyes.
