Explain haplontic and diplontic life cycle briefly

Haplontic life cycle — the haploid stage is multicellular and the diploid stage is a single cell, meiosis is "zygotic".

Diplontic life cycle — the diploid stage is multicellular and haploid gametes are formed, meiosis is "gametic".

haplontic life cycle

The plant body is gametophyte (haploid) and sporophyte (diploid) stage is represented only by zygote. The gametophytic plant develops haploid gametes in the gametangium. The fusion between gametes results the formation of zygote, the only diploid stage i.e., sporophytic phase of the life cycle.

The zygote undergoes meiotic division and forms four meiospores. These meiospores develop into haploid plants. The alternation of generations can be interpreted by chromosome number

diplontic life cycle

In this type the haploid and diploid phases are equally prominent and are represented by two distinct vegetative individuals. They differ only in chromosome number and function. The haploid gametophytic plant reproduces by sexual method, while diploid sporophytic plant by asexual process. In this life cycle alternation of two vegetative individuals occurs by sporogenic meiosis and fusion of gametes.

1) It is an intermediate type of life cycle, where both the sporophyte and gametophyte are multicellular, equally dominant and often free-living. Bryophytes and pteridophytes exhibit this pattern.

2) In Bryophytes, the dominant phase is the independent, photosynthetic, thalloid or erect haploid gametophyte and it alternates with the short-lived multicellular sporophyte totally or partially dependent on the gametophyte for its anchorage and nutrition.

3) In pteridophytes, the dominant phase is represented by the sporophyte which is diploid, independent, photosynthetic vascular plant body. It alternates with multicellular, independent but short-lived haploid gametophyte.

4) Algae exhibit haplontic life cycle but some of them such as Ectocarpus, Polysiphonia, Kelps are haplo-diplontic.

answer:

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.

Explanation:

hlo here is ur answer

Haplontic Life Cycle

A zygotic meiosis is a meiosis of a zygote immediately after karyogamy, which is the fusion of two cell nuclei. This way, the organism ends its diploid phase and produces several haploid cells. These cells divide mitotically to form either larger, multicellular individuals, or more haploid cells. Two opposite types of gametes (e.g., male and female) from these individuals or cells fuse to become a zygote.

In the whole cycle, zygotes are the only diploid cell; mitosis occurs only in the haploid phase.
