What is it about?
Fluid flow inside plant cells is called protoplasmic streaming. For a long time (45 years) ago, the velocity distribution was experimentally measured by the Laser light scattering technique, and two different peaks were reported. Langevin and Navier-Stokes simulations successfully reproduce these experimentally observed peaks.

Why is it important?
Our simulation data indicate that the non-uniform velocity distribution is caused by the Brownian motion of fluid particles. This result implies that statistical mechanical treatment is necessary for the protoplasmic streaming and analyses its biological function.
