Detailed explanation-1: -Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
Detailed explanation-2: -Fern Sori. Sori (singular: sorus) are groups of sporangia (singular: sporangium), which contain spores. Sori are usually found on the underside of the blade.
Detailed explanation-3: -Fern spores hydrate slowly but dry rapidly at ambient relative humidity. Low Brunauer–Emmet–Teller monolayer values, few water-binding sites according to the D’Arcy–Watt model, and limited solute–solvent compatibility according to the Flory–Huggins model suggest that fern spores have low affinity for water.
