Compare and contrast the processes of spermatogenesis and oogenesis. Include in your answer, two major differences between the final haploid sperm cell and the final haploid egg cell

Question

What will be an ideal response?

Answer 1

Answer: Spermatogenesis occurs completely within the testes and is a process that is continuous. It begins when puberty hits. Per one spermatocyte, four spermatozoa are produced. Their growth phase also tends to be short. On the other hand, oogenesis occurs in the ovaries and the last stage is in the oviduct. Unlike spermatogenesis, oogenesis is a discontinuous process. Early stages actually take place in the foetus. Per one oocyte, one ovum is provided. It also has 2-3 polar bodies and the growth phase tends to be prolonged. The main difference between a sperm and an egg cell is that sperm is a motile male gamete that has little reserve for food. It is also small in size compared to an egg cell and its nucleus goes through condensation. A mature edge cell is non-motile and is a female gamete. It has a large reserve for food compared to sperm. It also is larger in size and its nucleus does not go through condensation.
