diploid
Diplontes refers to all organisms whose somatic cells always contain a double set of chromosomes, that is, all cells except the germ cells, from which the ever-haploid gametes form. The haplists are opposed to the diplomats, whose cells have a simple set of chromosomes. In the diplons, only the germ cells that are specialized for the germ line pass through the meiosis, in which the chromosome set is divided in such a way that each haploid daughter cell receives a homologous partner of a chromosome pair. After another cell division, four gametes are produced. These haploid cells fuse together with the gametes of the partner during the reproduction into a diploid zygote, from which the new diploid form of life develops. All higher animals are diplomats. All plants, from the mossy plants to the fern plants to the vascular plants, undergo a change of generations, with two generations, a haploid and a diploid generation alternating. Since the vascular plants have greatly reduced the haploid generation, one can also regard them as diplonates.
