The answer is alternation of generation. It occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct sexual haploid and asexual diploid stages. The relationship between the sporophyte and gametophyte varies among different groups of plants. In those algae which have alternation of generations, the sporophyte and gametophyte are separate independent organisms, which may or may not have a similar appearance. In liverworts, mosses, and hornworts, the sporophyte is less well developed than the gametophyte and is largely dependent on it. In all modern vascular plants the gametophyte is less well developed than the sporophyte.
The correct answer for the question that is being presented above is this one: "Protista." <span>In the new 6-kingdom system of classification, like the old 5-kingdom system, organisms are basically grouped by what is called Protista. Protista is the kingdom that contains anything that isn't classified as an animal, plant, fungi or bacteria.</span>
Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.
