Cytoplasmic streaming in Chara corallina. (A) Internodes and branchlets of Chara. Individual internodes can grow up to 10 cm long. (B) Rotational streaming in a single internodal cell of Chara. The stripes indicate the polarity of actin cables at the periphery driving flow in the cytoplasm and vacuole. (C) Microscopic mechanism driving plant cell streaming. Cargo-carrying myosin motors bind to actin filaments and entrain flow as they walk.
