What is the term for the sperm cell at the end of meiosis?

The term used to describe the sperm cell at the end of meiosis is "spermatid." During the process of spermatogenesis, which involves the two rounds of meiotic division, diploid spermatogonia differentiate into haploid spermatids. Each spermatid undergoes further morphological changes and maturation to become a fully functional sperm cell, known as spermatozoa.

While spermatozoa refers to the mature sperm cells ready for fertilization, spermatids specifically denote the cells that have just resulted from the meiotic divisions and are in the process of developing into spermatozoa.

Spermatocytes, on the other hand, refer to the cells that undergo meiosis and include both primary and secondary forms, but are not the final stage after meiosis. A zygote is the fertilized egg resulting from the fusion of a sperm and an egg, which occurs after meiosis has taken place in the male gamete.
