Cell that are Haploid posses a single set of chromosomes. Haploid describes a cell that contains a single set of chromosomes. In humans, gametes (sperms and eggs) are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diploid cells. On the other hand, Human cells like skin, lung, kidney, etc are diploid, which means they have two sets of chromosomes (23 from each parent to make 46 chromosomes).
