Mitotic Division Resulting in Eight Blastomere : Photograph, actual size of zygote = 0.2 mm approx. - This image depicts the zygote, which has undergone two mitotic divisions. Four cells, also called blastomeres, can be seen. They are all indicated in gray-green with a white-purple outline. Divisions will continue as the blastomeres move down the fallopian tubes and to the uterine cavity.
In biology, a blastomere is a type of cell produced by cleavage (cell division) of the zygote after fertilization and is an essential part of blastula formation.
