Detailed explanation-1: -So, the correct answer is ‘spore formation’.

Detailed explanation-2: -Hint: Meiosis in ferns occurs at spore formation. Where the plant body is sporophyte differentiated into leaves, stems and roots. Ferns undergo meiosis to form haploid spores. The life cycle of ferns is sporophyte and gametophyte, which releases gametes.

Detailed explanation-3: -The zygote develops as a multicellular sporophyte, but remains dependent on the female gametophyte. Meiosis takes place in a specialized structure on the sporophyte (the sporangium), producing spores (not gametes!). The spores divide and produce male or female gametophytes. The sporophyte of mosses: a dependent stage.

Detailed explanation-4: -Solution : In pteridophyte or ferns or Dryopteris meiosis occurs in spore mother cell during spore formation.

Detailed explanation-5: -Unlike some other non-flowering vascular plants, ferns produce one type of spore (homosporous) via meiosis in the sac-like sporangia. Within each sporangium, the diploid spores (spore mother cells or sporocytes) undergo meiosis.
