Observation on The Precess of Fertilization of Haliotis discus hannai With Transmission Electron Microscope

This thesis studied the process of fertilization of the abalone (Haliotis discus hannai) with transmission electron microscope (TEM).The jelly coat of abalone egg activated spermatozoa and induced acrosome reaction.The vitelline membrane promoted the acrosome reaction reach the climax.After the sperm entered the egg,the egg cortical reaction took place and the fertilization membrane was formed.Afterwards,the eggs meiosis began.Besides,we found polyspermy of the abalone.
