Question
In which type of life cycle sporophyte generation is represented only by one-celled zygote?
Haplontic
Diplontic
Haplo-diplontic
None of the above
Haplontic
Diplontic
Haplo-diplontic
None of the above
Hint:
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
