What kind of development takes place in zygote in organisms with haplontic life cycle

Answer 1

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. 
As shown in figure, the zygote undergoes mitotic division to form multicellular d
