Is a sperm cell dipliod

Somatic cells , tissues , and individual organisms can be described according to the number of sets of chromosomes present the "ploidy level" : monoploid 1 set , diploid 2 sets , triploid 3 sets , tetraploid 4 sets , pentaploid 5 sets , hexaploid 6 sets , heptaploid [2] or septaploid [3] 7 sets , etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle. Half of all known plant genera contain polyploid species, and about two-thirds of all grasses are polyploid. In some species, ploidy varies between individuals of the same species as in the social insects , and in others, entire tissues and organ systems may be polyploid despite the rest of the body being diploid as in the mammalian liver. For many organisms, especially plants and fungi, changes in ploidy level between generations are major drivers of speciation.
