title: Injection of foreign particles and their intracellular translocation in living phloem fibers.
abstract: Droplets of castor oil 5-10 μ in diameter were injected into individual cells of living differentiated phloem fibers. The droplets retained their integrity and their movement was recorded on 16-mm movie film. These foreign particles were translocated, along with indigenous particles, by the rotational cytoplasmic currents of the fibers.
