Expert Answer
- Different plant groups exhibit different patterns in their life cycles.
- Usually, they have two phases—a haploid phase, i.e. a gametophyte phase, and a diploid phase, i.e. a sporophyte phase.
- Both phases alternate with each other. This is called alternation of generations.
- Different patterns of alternation of generations have been observed in different groups of plants, based on the length of the haploid and diploid phases.
- Alternation of generations, however, is not associated with the number of haploid and diploid phases.
