Question

Are Bryophytes Haplodiplontic?

Answer 1

Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. This type of life cycle is called a haplodiplontic life cycle. The amphibians of the plant kingdom reproduce sexually with the aid of the fusion of gametes resulting in the zygote that types into a sporophyte instead of present process meiosis. Bryophytes' lifestyles cycle contains each haploid and diploid cell.

Complete answer:
In bryophytes the predominant plant physique is haploid and it produces gametes, consequently known as gametocyte. They include multicellular, stalked, and jacketed intercourse organs. Antheridium is the male sex organ. Archegonium is the lady sex organ. Antheridium produces biflagellate antherozoids. The lady sex organ produces a single egg. it is flask-shaped. Male gametes are released into the water where they fuse with the lady gamete.

Their fusion outcomes in the formation of a zygote. This is referred to as zooidogamous oogamy. In bryophytes, the formed zygote does not undergo meiosis immediately. It produces sporophyte which is a multicellular body, free-living but connected to the photosynthetic gametes for an energy source. Some of the cells (spore mom cells) bear meiosis and produce haploid cells which similarly
germinate to produce gametophyte.

All bryophytes are homosporous. They show heteromorphic alternation of generations due to the fact gametophytic and sporophytic bodies are conspicuously different. They show a haplo-diplontic existence cycle.

So, yes bryophytes are haplodiplontic.

Note:
- Bryophytes normally have much less economic importance but some bryophytes like mosses provide meals for herbaceous animals, birds, and other mammals.
- Sphagnum, usually known as peat moss is used as a gasoline and also used as packing cloth for transhipment of living material because of its capacity to hold water.
- Hepaticopsida(liverworts), anthocerotopsida(hornworts), and Bryopsida(mosses) are the three training
