Question

what is mean by haploid spore?

and what is its relation with sporophyte?

Answer 1

• 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.
