In multicellular animals and plants the single-celled zygote develops into the embryo. However, observation of zygote division in living material in real time is difficult owing to the restricted ...

An international group of plant biologists has succeeded for the first time in visualizing how egg cells in plants divides unequally (asymmetric cell division) after being fertilized. The direction of ...

Researchers discover that separate pronuclei in fertilized eggs create a competitive environment essential for maintaining ...

The process of embryogenesis begins with an egg or ovum being fertilized by a sperm cell to form a zygote. The zygote is a single diploid cell, which will ultimately multiply through mitotic division ...
