NEET BIOLOGY

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: -Through the process of meiosis, the sporophyte produces haploid spores in the flower. The spores are the gametophytic generation. Meiosis occurs in the male flower parts to produce pollen (represented by the green circle) and the female floral organs produce egg cells (represented by the white circle).

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.
