Most of the algae such as Volvox, Spirogyra, etc. (C) Life cycles may alternative between haploid and diploid mitotic phases and may show morphological differences . The types are: 1. 2) Gametes are haploid and called a gametophyte. Therefore, the only diploid cell formed during thehaplonticlife cycle is the zygote. ins.style.width = '100%'; Hence, theorganism ends up in a haploid stage. Haploid cells divide mitotically to produce new plants. An alga which exhibits diplontic life cycle This way, the organism ends its diploid phase and produces several haploid cells. Fucus has dichotomous branches which have heart shaped swollen reproductive tips. Most animals are diplontic and undergo mitosis only in the diploid generation (paths B and (more) All plants alternate generations. The fucus has a diplontic life cycle. the gametophytic phase is prominent (60%) in their life cycle Diploid sporophyte cells undergo meiosis to produce haploid spores. The main difference between haplontic and diplontic life cycle is that the main form of the haplontic life cycle is haploid and its diploid zygote is formed for a short period of time whereas the main form of the diplontic life cycle is diploid, which produce gametes. The zygote grows by mitosis into a diploid, multicellular organism. In Diplontic lifecycle, the zygote undergoes mitosis. This ensures that the gametes will have only one set of chromosomes, so when they fuse again during sexual reproduction, the resulting zygote will have the two sets of chromosomes of a normal diploid cell. Is Haplodiplontic and Diplohaplontic life cycle same? The cells of the diploid organism divide by meiosis to form the haploid gametes. These are dominant and each spore divides further to form a gametophyte. In the whole cycle, zygotes are the only diploid cell; mitosis occurs only in the haploid phase. Was this answer helpful?
