explain haplo-diplontic.
with example
Answers
Heya user.......
Haplo-Diplontic lifecycle is seen in Bryophytes....
The reproductive organs grow on the sporophyte...
The egg(female gamete) of Archegonium (Female reproductive organ) fuses with the biflagellate antherozoids(male gametes) released by Antheridium(Male reproductive organ) to produce the zygote...
Zygote produces a multicellular body called sporophyte...
The sporophyte is not free living but attached to the photosynthetic gametophyte and derives nutrition from it ...some cells of the sporophyte called spore mother cells undergo reduction division to produce haploid spores.These spores germinate to produce gametophyte...
All the Bryophytes are homosporpus...
They show heteromorphic alternation of generations and thus the life cycle is haplo-diplontic...
Hope this helps you :)

Haplo diplontic-------Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. This type of life cycle is called a haplodiplonticlife cycle. It differs from our own diplontic life cycle, in which only the gametes are in the haploid state.
