prominent examples are blood cells, which can be further subdivided into oxygen-transporting “red” blood cells (erythrocytes) and “white” blood cells (leukocytes), which engage in different tasks in immunity. Cell motility is mostly passive and based on the blood stream. However...
This process is called cytoplasmic streaming. In plants, it is driven by motor pro- teins that travel along cytoskeletal elements [206], while in fungal cells it is based on osmotic pressure differences [154]. It is believed that cytoplasmic streaming compen- sates for the larger size and ...
