Question
Differentiate between haplontic and diplontic life cycles.
✓

Answer

The gametes fuse and give rise to diploid zygote. Meiosis in the zygote results in the formation of haploid spores. This is haplontic life cycle.
In diplontic life cycle, diploid sporophyte is dominant. Zygote develops into an embryo and then into a sporophyte.
