Sperm are male sex cells. You might also hear them referred to as reproductive cells, or gametes. They fertilize female sex cells, called eggs or ova, which results inpregnancy. Parts of sperm The head.This part of the sperm carries 23 chromosomes, which contain all the genetic information ...
Perhaps unsurprisingly, data on such microscopic eggs are hard to find. According to the 1994 review, a tiny parasitoid fly called Clemelis pullata has the smallest eggs known. They measure 0.027mm by 0.02mm. However, nobody has yet studied the sex cells of miniature parasitic wasps known as...

And second male gamete fuses with the egg cell called syngamy. Answer and Explanation: Syngamy results in the formation of the zygote, the primary sporophytic cell of the plant. Zygote gives two cells, apical and basal cell. The apical......
Introduction The production of gametes is a biological process occurring in organisms that sexually reproduce. Females make gametes called eggs, and males make gametes called sperm. Both egg and sperm cells begin as identical germ cells and are produced through a process of cell division called meio...
They are also referred to as sex cells. Female gametes are calledova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis. ...
The majority of cytoplasm in round spermatids is enclosed within cytoplasmic vesicles called residual bodies, which are engulfed by Sertoli cells and degraded18. 80 S ribosomes are removed as a component of the residual body19. As cytosolic translation has ceased in sperm, intact long RNAs are...
are many randomly scattered cells, calledSertoli cells, that function to support and nourish the immature sperm cells by giving them nutrients and blood products. As the young germ cells grow, the Sertoli cells help to transport them from the outer surface of the seminiferous tubule to the centr...
Scientists say they have coaxed uncommitted mouse embryonic stem cells to grow into sperm cells in the laboratory.
