HORTICULTURE

Detailed explanation-1: -In the majority of algae and fungi, all structures are haploid except the zygote which is diploid. The haploid phase is called the gametophytic phase, whereas the diploid stage in the life cycle is called the sporophytic phase.

Detailed explanation-2: -Most fungi and algae employ a haploid-dominant life cycle type in which the “body” of the organism is haploid; specialized haploid cells from two individuals join to form a diploid zygote.

Detailed explanation-3: -The haploid form produces gametes and is called a gametophyte. The diploid organism produces spores and is called a sporophyte. Note that both spores and zygotes show ‘developmental potential’. Spores divide and produce a haploid colonial filament (the gametophyte).
