The major difference between the two is the amount of cytoplasm. The polar bodies have a lot less cytoplasm than an ovum has.
a polar body is A small cell (which eventually disintegrates) that is the by-product of meiosis in female animals. One functional ovum and potentially three polar bodies result from meiosis of each primary oocyte. By:hyden 252-1079 im bored

ovum
The oocyte (immature ovum or egg). It produces a secondary oocyte (large, lots of cytoplasm) and a polar body (small, does not survive).
When an ovum is initially formed by the normal process of cell division, it is diploid. In order to become a gamete that can engage in sexual reproduction, it needs to become haploid. In order to do that it has to rid itself of half of its genetic material, which it does by ejecting it in the form of a polar body. Note that it is not feasible for the ovum to simply become two ova, because that would give you half sized ova, and reproduction works better with a full sized ovum.
ovum
One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
Generally, one viable ovum(egg) is produced, while the other three cells degenerate into 'polar bodies' and are recycled by the body.
For the human body, the female ovum.
Men = sperm Women = ovum (egg)
Electrons are shared unequally in a polar bond.
