Question

what is the difference between an oocyte an a primary oocyte?

Answer 1

in actual there is not a much differnce bcz both are immature form of ova...bt we can say oocyte as primary oocyte when it has started to develp....

Answer 2

1.primary oocytes
- diploid (2 complete sets of chromosomes)
- 'formed' from oogonia during the process of oogenesis
* primordial follicles consist of a primary oocyte + a single layer of squamous follicle cells
* primary follicles consist of a primary oocyte + 1/several layers of cuboidal follicle cells

2. secondary oocytes
- haploid (1 complete set of chromosomes)
- developed from the primary oocyte undergoing meiosis I to form a secondary oocyte + a tiny first polar body
* found in the matured Graafian follicle
* begins meiosis II & stops at metaphase II upon ovulation & only continues upon fertilisation
