Cytoplasmic streaming
Cytoplasmic Streaming
Cytoplasmic streaming, also known as cytoplasmic flow or cyclosis, is a cellular process that involves the movement of the fluid substance (cytoplasm) within a plant or animal cell. The process is an essential aspect of cell biology and plays a crucial role in nutrient transportation and cellular metabolism.
Pronunciation
Cytoplasmic streaming: /ˌsaɪtoʊˈplæzmɪk ˈstriːmɪŋ/
Etymology
The term "cytoplasmic streaming" is derived from the Greek words "kytos" meaning "hollow vessel", "plasma" meaning "something formed or molded", and the English word "streaming".
Process
Cytoplasmic streaming involves the movement of organelles and other cellular contents in a directed manner within the cell. This movement is facilitated by actin filaments and myosin motor proteins, which form a network of tracks for the transport of organelles and vesicles.
Function
The primary function of cytoplasmic streaming is to facilitate the distribution of nutrients, metabolites, and genetic material within the cell. It also aids in cell growth, cell division, and the maintenance of cell shape.
Related Terms

- Ectoplasm: The outer non-granulated layer of the cytoplasm that is involved in cellular locomotion and shape changes.
- Actin: A protein that forms microfilaments and is involved in muscle contraction and other types of cell movement.
- Myosin: A type of motor protein that interacts with actin to cause cell movement.
