Answer:
Haplodiplontic life cycle includes a multicellular haploid stage.
Explanation:
Haplodiplontic life cycle:
- The multicellular haploid gametophyte (from the Greek phyton, "plant") produces gametes. A multicellular diploid sporophyte is created through fertilisation, and through meiosis, it creates haploid spores. A haplodiplontic life cycle is the name given to this kind of cycle.
- Gametes are not a direct outcome of a meiotic division in haplodiplontic life cycles. Meiosis occurs in diploid sporophyte cells to create haploid spores. A multicellular, haploid gametophyte is produced by the mitotic division of each spore.
- A clear generational transition occurs between a gametophyte that produces haploid gametes and a sporophyte that produces diploid spores in a haploid-diplontic life cycle. This type of life cycle pattern is shared by pteridophytes and bryophytes.
Can haploid cells divide by mitosis or by meiosis?
Mitosis can occur in haploid and diploid cells. When a haploid cell divides, it creates two daughter cells that are genetically identical to one another; when a diploid cell divides, it creates two daughter cells that are genetically identical to one another.
Thus, Gametophytes are haploid multicellular plants (or algae) that use specialised cells to produce gametes, hence the name "gametophytes."
