What is the function of the gametophyte generation of the fern plant? not multiple choice.
produces reproductive organs which produce a zygote
produces meiospores which grow into a sporophyte plant
produces a new fern asexually
grows as a diploid fern

That would be A. Produces reproductive organs which produce a zygote.

Zygotes grow into the sporophyte(diploid), spores grow into the gametophyte(haploid).

Sporophyte produces haploid spores through meiosis, gametophyte produces gametes through mitosis.
