Question

In which type of life cycle sporophyte generation is represented only by one-celled zygote?

  1. Haplontic

  2. Diplontic

  3. Haplo-diplontic

  4. None of the above

hintHint:

The life cycle exhibited by algae.

The correct answer is:

Haplontic


    • Zygote is the only diploid cell in the lifecycle of green algae
    • Theses organisms follow haplontic lifecycle 
    • Haploid gametophyte is dominant in haplontic life cycle
    • The diploid zygote formed will divide by meiosis forming haploid cells
    • The haploid cells will develop into a multicellular organism
    • Spirogyra, Chlamydomonas, Volvox are few example of green algae exhibiting this life cycle

    • Green algae follow haplontic life cycle
    • Gametophytes are dominant
