What kind of development takes place in the zygote in organisms with diplontic and haplo-diplontic life cycles
Answers
Explanation:
Diplontic Life cycle:In this type of life cycle, Diploid zygote, germinates by mitosis to form unicellular or multicellular diploid sporophyte. All seed- bearing plants i.e. gymnosperms and angiosperms, follow this pattern. Haplontic life cycle: In most of the plants, the zygote undergoes mitotic cell division and produces diploid sporophytes. The sporophyte divides meiotically to produce haploid spores. These spores again undergo mitotic cell division and produce haploid gametophytes. This gametophyte produces gametes by mitosis. This type of life cycle is known as Haplodiplontic Life Cycle.
Answer: In diplontic life cycle, diploid zygote, germinates by mitosis to form unicellular Or multicellular diploid sporophores. All seed bearing plants that are gymnosperms and angiosperms follow this pattern
In haplontic life cycle,in most of the plants, the zygote undergoes mitotic cell division and produces diploid sporophores. The sporophores divides mitotically to produce haploid spores again undergoes mitotic cell division and produce haploid gametophyte. The gametophyte produces gametes by mitosis . This type of life cycle is known as haplodiplontic life cycle
