Cytoplasmic fibres associated with streaming and saltatory-particle movement in Heracleum mantegazzianum.
The giant cells of the petiolar hairs of Heracleum mantegazzianum contain cytoplasmic fibres that are readily visible with phase contrast or interference contrast optics. These fibres are associated with saltatory particle movement and protoplasmic streaming in this cell and are believed to be the living image of similar fibres reported in electron micrographs of a variety of cell types.
