Oocytes- Female Reproductive Cells
Oocytes are haploid cells, found in the ovary that might undergo meiotic division to form an ovum. A vitelline layer coated with protein receptors lines the outside of the egg plasma membrane of an oocyte. Cortical granule content lines the inside of the plasma membrane that form into cortical granule vesicles. Oocytes have all the same organelles of a typical eukaryotic cell but are specialized towards making an ovum during a female reproductive system and are present in females until menopause. Oocytes are classified under ovarian tissue.

I really like this but would like if it was little longer describing each answer alittle more. Overall, this was a pretty good post!
ReplyDeleteThank you!! Yea I wish I had more time to go in detail, will work on that in the future. :)
DeleteInteresting post, though I think it would be helpful if you defined the terms you used (like meiosis and ovum) so that people who do not know so much of biology can also understand it. Also, you say that "oocytes...are present in females until menopause." Does that mean that oocytes can no longer be found in a female once she has entered menopause?
ReplyDeleteYea I'm sorry for not defining it in more detail.
DeleteMeiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes for reproduction.
An ovum is a mature female reproductive cell that can divide and give rise to an embryo usually only after fertilization by a male cell. So a bunch of oocyte cells are found in the the ovum.
And women experience menopause over a few months or even years, so gradually women do lose all of their oocytes because they no longer have a need for them. Their body doesn't need oocyte cells because they can't reproduce anymore.
I hope that answered all your questions :)
