Question

Explain cytoplasmic streaming and its function in the cell?

Answer 1

answer:

Cytoplasmic streaming, also called protoplasmic streaming and cyclosis, is where there is flow inside the cytoplasm. It is typically observed in large plant and animal cells. Here flow means that the cytoplasm is moving inside the cell, it is not stationary. The flow is driven by forces from the cytoskeleton, and it is likely that the function of flow is at least partly to speed up transport of molecules and organelles around the cell. Cytoplasmic streaming is usually found in unusually large cells, greater than approximately 0.1 mm. In smaller cells, diffusion of molecules will be rapid but diffusion slows rapidly as the size increases, and so larger cells may need flow to move nutrients etc.
