According to Strasburger ('92) the process of division in the development of the swarm-spores, which is exactly the same for the gametes, differs from the beginning in a very marked way from the vegetative cell-divisions. At first the cell-contents undergo apparently a sort of rejuvenescence by which the protoplast becomes independent of both the outer and inner plasm D E.
