asymmetric cell division

[¦ā·sə‚me·trik ′sel də‚vizh·ən]
(cell and molecular biology)
A phenomenon in which a mother cell divides into daughter cells that are unequal in size or cytoplasmic content, usually resulting in a different developmental fate for each.

During female germ cell meiosis, asymmetric cell divisions take place to ensure that most of the maternal stores are retained within the oocyte, resulting in the formation of daughter cells with different sizes: the large oocyte and the small polar bodies.
In animal science, the investigation of asymmetric cell division is a major area of study but in plant science, almost nothing is known about it," he said.
