Cell Membrane Fusion and the Fertilization Mechanism in Plants and Animals.
Plasmatic fusion in both plant and animal fertilization seems to start with the coalescence of cell membranes of the gametes. In male gametes, the area of fusion is predetermined: in some algae it is the flagellar tip, while in animal organisms it is the acrosome filament. These organelles thus fulfill comparable roles in the mechanism of fertilization.
