Plant cells are surrounded by a cell wall composed of polysaccharides and hence can change neither their form nor their position. However, active movement of organelles (cytoplasmic streaming or protoplasmic streaming) is observed in plant cells, and involvement of the actin/myosin system in these processes has been suggested. Successful biochemical and biophysical approaches to studying myosins have extensively promoted the understanding of the molecular mechanism underlying these phenomena.
植物细胞被由多糖组成的细胞壁所包围，因此既不能改变其形态，也不能改变其位置。然而，在植物细胞中观察到细胞器的活跃运动（细胞质流动或原生质流动），并且有人提出肌动蛋白/肌球蛋白系统参与了这些过程。研究肌球蛋白的成功的生化和生物物理方法极大地促进了对这些现象背后分子机制的理解。
