Question
Haplo-diplontic life cycle is found in ____________.
Bryophytes
Pteridophytes
Fungi
Both A and B
Bryophytes
Pteridophytes
Fungi
Both A and B
Hint:
Any phase can be dominant in these organisms following haplo-diploid life cycle.
The correct answer is: Both A and B
- Alteration of generation is the lifecycle followed by plants and algae
- Alteration of generation involves alteration of sporophyte and gametophytic phases
- The organisms can follow haplontic, diplontic or haplo-diplontic lifecycle
- Fungus and bryophytes follow haplo-diplontic lifecycle
- In haplo-diplontic lifecycle, both diploid and haploid stages are multicellular
- In bryophytes, gametophyte is dominant and sporophyte is dependent on it
- In fungus, sporophyte is dominant phase
- Alteration of generation is the rotation of sporophyte and gametophyte phases
- Organism can follow either haplontic or diplontic or haplo-diplontic lifecycle
- Green algae follow haplontic lifecycle
- Fungus and bryophytes follow haplo-diplontic lifecycle
- Angiosperms, gymnosperms follow diplontic lifecycle
