What type of cells are gametes?
[ "reproductive", "cardiac", "immune", "proteins" ]
A
Sperm are male gametes, or reproductive cells. Sperm form when certain cells in the male reproductive system divide by meiosis to form haploid cells. Being haploid means they have half the number of chromosomes of other cells in the body. An adult male may produce millions of sperm each day!.
