NEET repeatedly tests two traps in the bryophyte-pteridophyte pair: which generation is dominant and free-living, and which genera are heterosporous. In bryophytes the plant body you see is the gametophyte — haploid, photosynthetic, free-living; the sporophyte it produces stays attached to it, drawing nourishment for its whole existence and never becoming independent. In pteridophytes this reverses: the visible plant — with true root, stem, leaves and vascular tissue — is the sporophyte, the dominant free-living phase, while its gametophyte is a small, inconspicuous, free-living thalloid prothallus needing cool, damp, shady ground and standing water so antherozoids can swim to the archegonium.
Within bryophytes, liverworts (Marchantia) and mosses (Funaria, Polytrichum, Sphagnum) differ in more than habitat: a moss gametophyte runs through two stages — a filamentous protonema germinating directly from the spore, then a leafy shoot arising from it as a lateral bud — while a liverwort thallus skips that intermediate. Both groups build a sporophyte from the same three parts, foot, seta and capsule, but NCERT is explicit that the moss sporophyte is the more elaborate of the two.
Within pteridophytes, spore type is the second trap. Most genera are homosporous, releasing spores of one kind; Selaginella and Salvinia are the named exceptions, producing macrospores and microspores that germinate into separate female and male gametophytes — and in these genera the female gametophyte stays attached to the parent sporophyte, with the embryo developing inside it, a step NCERT flags as a precursor to the seed habit. The four pteridophyte classes — Psilopsida (Psilotum), Lycopsida (Selaginella, Lycopodium), Sphenopsida (Equisetum), Pteropsida (Dryopteris, Pteris, Adiantum) — are a separate fact: don't let a genus's spore type decide its class, or vice versa.
Watch out: antheridium and archegonium are named the same way in both groups — antheridium (male) makes biflagellate antherozoids, archegonium (female) is flask-shaped and makes one egg — so a swapped label is a swap you can catch by shape and product alone.
