Relation of the male gametes with embryo sec cells. The hypothesis of double fertilization

N. S. Belayeva

Abstract


The sperms one after another get out of synergids. The front sperm gets the first into the egg cell attraction zone and then the sperm comes into contact with egg membrane. At this moment Attraction ceases and the second sperm is led by a current of cytoplasma to the central nucleus. In the egg cell the sperm nucleus is led to the nucleus by cytoplasmic current too. After fertilization the character of cytoplasmic motion changes, because of a cell membrane damage. The presence of the sperm in the female nuclei may also serve as a regulating factor.
