Pteridophyte Classification & Features — NEET Biology
✅ Asked in NEET 2023The pteridophytes are further classified into four classes: Psilopsida (Psilotum), Lycopsida (Selaginella, Lycopodium), Sphenopsida (Equisetum) and Pteropsida (Dryopteris, Pteris, Adiantum).
NTA tests this topic through questions on pteridophyte classes and their representative genera. Students often confuse which genus belongs to which class—for example, mixing up Selaginella (Lycopsida, heterosporous) with Lycopodium (Lycopsida, homosporous). The key trap: assuming all members of the same class share identical characteristics like spore type. To get it right, memorize that Lycopsida includes both homosporous (Lycopodium) and heterosporous (Selaginella) plants, while other classes like Sphenopsida (Equisetum) and Pteropsida (Dryopteris) have their distinct features. Focus on heterospory in Selaginella—it's frequently tested as a unique adaptation.
