- Good morning, Future Biologists! Answer sheets are now distributed you can now start answering.
- Time is up. Submit your answers here in front.
- Not all. I find some items hard especially the gametogenesis one.
- Did you answer the items correctly?
- Do you want me to explain it to you while on our way home?
- Really? Sure!
- Gametogenesis is the forming of sperm (spermatogenesis) and eggs (oogenesis), this happens during the meiotic phase.
- Throughout the process of spermatogenesis, diploid spermatogonia undergo mitosis until they proceed to transform to gametes. One of the resulting gametes finally becomes a primary spermatocyte, after which it will divide once during the first meiotic phase to produce two haploid secondary spermatocytes.
- Every one of the secondary spermatocytes will undergo a second meiotic division to give rise to two spermatids, which will later gain flagella and grow into mature sperm. With in course of oogenesis, diploid oogonium undergo mitosis until one matures into a primary oocyte.
- This oocyte would then proceed the first meiotic division but then apprehend; it will complete this division as it matures in the follicle, gives way to a haploid secondary oocyte and a tinier polar body. The secondary oocyte starts the second meiotic division but then pauses once again. When a sperm fertilizes, it will continue the division, producing a mature ovum as well as another polar body.
- Thank you for that. That was of big help. The bus is here. I'll go now. See you tomorow!
