Question

Differentiate between halplontic and diplontic life cycle

Answer 1

In diplontic life cycle, diploid sporophyte is the dominant, photosynthetic, independent phase of the plant. The gametophytic phase is represented by the single celled (gametes) to few-celled haploid gametophyte. In Diplontic lifecycle, the zygote undergoes mitosis.(An organism having somatic cells with the diploid number of chromosomes).

Haplodiplontic life cycle is an intermediate condition between haplontic and diplontic life cycle.Both gametophyte and sporophyte are free-living and multicellular, but have different dominant phases.

Answer 2

In Halplontic cell gametes are formed by mitosis these gametes are haploid(n) so in this type of life cycle the zygote phase is only diploid(2n) and remaining all the phase are haploid(n) so this type of life cycle is known as Halplontic life cycle
