Cytoplasmic Motion in Elodea

To date laser light scattering has been used to study cytoplasmic streaming in lower plants only, examples being algae1 and slime moulds2. We report here preliminary experiments using photon correlation to study cytoplasmic motion in the higher plant Elodea canadensis. Apart from possible evolutionary advances in higher plants, the cells are very different from those in lower plants and so differences in the streaming behaviour may be expected. Observations were made on detailed leaves of Elodea and streaming was observed in most leaf cells, velocities from 0.5 μm/s to 10μm/s being measured under different conditions. Diffusive motion of the cytoplasmic material was also apparent.
