What is the advantage of unequal cytoplasmic division during oogenesis?

∙ 11y ago
Oogenesis (the creation of an ovum, an egg cell) takes one cell and makes four. But only one cell is eventually used as a gamete. It would be inefficient to allow the three other cells equal amounts of cytoplasm or nutrients if only one of those cells is the important one. Therefore, all resources from the original cell goes to the ovum, while the three other cells are just a depository for DNA. The three other cells are called polar bodies and will then die soon after.

actually it is polar body

What is the difference between spermatogenesis and oogenesis?
Spermatogenesis takes place in the testes of males, oogenesis takes place in the ovary of the females.Spermatogenesis produces small, motile spermatozoa whereas in oogenesis the ovum is spherical, not motile and is much larger with more food reserves and cytoplasm.Spermatogenesis involves a metamorphosis stage called spermiogenesis, in oogenesis there is no metamorphosis stage.In spermatogenesis, 4 gametes are produced from each meiotic division, whereas in oogenesis there is only 1 gamete produced from each division as the unequal cytokinesis leads to the formation of polar bodies.Spermatogenesis occurs in males (human males) continuously from puberty to death whereas oogenesis starts in females in the fetal period. It takes 70 days for sperm to be produced in males.In oogenesis, the development of the oocyte is arrested at prophase I of meiosis until puberty, and then stops at metaphase II of meiosis until fertilization, where the meiotic division is finally completed. In males meiosis occurs continuouslyThe hormones in the 2 processes have different effects - in oogenesis, FSH is responsible for the choice of the primary oocyte and causes the cells of the membrana granulosa to proliferate to form the theca interna which secretes oestrogen, and the theca externa. LH in females stimulates ovulation and the maturation of the Graafian follicle. In males, on the other hand, FSH increases the activity of the Sertoli cells which are involved in spermiogenesis (the metamorphosis stage of spermatogenesis). LH in males stimulates the Leydig cells to secrete testosterone.
