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 ...

In most flowering plants, the asymmetric cell division of the zygote is the initial step in establishing the apical–basal axis of the mature plant. The zygote is polarized, possessing the nucleus at ...

Figure 1: Orientation of the first cleavage division. Figure 2: Cytochalasin treatment before pronuclei migration changes the orientation of the first cleavage division. Figure 3: Relationship between ...

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 ...
