Successive observations on the fertilization of a centric diatomMelosira moniliformis var.octagona

The details of fertilization in the centric diatom,Melosira moniliformis var.octagona, were examined by light microscopy with a video system. The sperm penetrated into the egg cell through a temporary opening of the oogonium. The flagellum of the sperm was brought into the egg cell and it remained active for a few minutes. Three observations on the behavior of the sperm and egg cell during fertilization are shown.
