Polar cell

Definition

noun, plural: polar cells

The cell that results from the asymmetric division of an oocyte.


Supplement

In animals and humans, polar bodies are produced every after meiotic division. They are relatively smaller in size due to less cytoplasm compared to the gametocyte that will become the ovum. This is essential so that much of the cytoplasm is available and the chromosomal content is halved at the time of fertilization. The polar bodies will eventually degenerate.


Also called: polar body
