Answer:
Spermiogenesis
Explanation:
Spermiogenesis is the stage during which the haploid spermatids are matured into sperms. It does not include any cell division.
The process of spermiogenesis includes elongation of spermatids and formation of acrosome at the top of its nucleus. A flagellum develops to make it a motile cell. There is an increase in the number of mitochondria while the excess of the cytoplasm is released outside.
All these events mature the haploid spermatid into a sperm cell having the capacity to reach and fertilize the egg.
