19 + Interview Questions in MAN GAMETOGENESIS IN GENERAL AWARENESS Page 1 InterviewSolution

1.	Name the hormones found on the surface of the egg.
Answer» Gynogamone & Fertilizin found on the surface of the egg.

Discussion

2.	Describe the formation of Acrosome
Answer» Formation of Acrosome: The anteriormost part of the sperm is called an acrosome. It is formed by the Golgi body during the spermiogenesis. Firstly, one of the vacuoles of the Golgi body develops an acrosomal granule. Gradually, the acrosomal granule accumulates lytic enzymes and forms a cap-like structure on the anterior end of the nucleus. Soon this cap gets bounded by a single unit plasma membrane and forms an acrosome. The rest parts of the Golgi body are lost in the form of Golgi rest.

Discussion

19.	Differentiate oogenesis and spermatogenesis.
Answer» Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas, oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into a embryo.
