Difference Between Diplontic and Haplontic Life Cycle

Content: Haplodiplontic Life Cycle – Here both haploid and diploid stages are multicellular. In some, the gametophyte is dominant and free-living and the sporophyte is a small and short-lived phase, which is dependent on gametophytes, e.g. Bryophytes. In pteridophytes, the sporophyte is the independent and free-living dominant stage. It alternates with short-lived gametophyte. Some algae such as Ulva, Polysiphonia, Ectocarpus, Kelps have a haplodiplontic life cycle. Difference Between Diplontic and Haplontic Life Cycle
Diplontic Life Cycle
Haplontic Life Cycle
Sporophyte (2n)
Dominant phase, which is independent, free-living and performs photosynthesis
Conspicuous and represented by Zygote or few celled sporophytes
Gametophyte (n)
Conspicuous and represented by gametes, i.e. egg cell and sperm or few-celled gametophyte
Dominant phase, which is independent, free-living and performs photosynthesis
Mitotic Division
The zygote divides mitotically to give rise to a new plant. Haploid cells divide mitotically to produce new plants. Meiosis Division
Gametes are produced by meiosis division. The zygote divides meiotically to form haploid cells, which proliferate by mitosis. Examples
Angiosperms, Gymnosperms, some algae such as Fucus, Cladophora, etc.
