Plant Classification & Key Differences — NEET Biology
📚 Practice ConceptDifferentiate between the following:- (i) red algae and brown algae (ii) liverworts and moss (iii) homosporous and heterosporous pteridophyte
Consider the following statements regarding classification and reproduction in algae and pteridophytes: 1. Chara belongs to Chlorophyceae; it shows oogamous reproduction with a large non-motile egg and smaller motile sperm. 2. Selaginella belongs to Lycopsida under Pteridophytes; it is heterosporous, producing both megaspores and microspores within compact strobili. 3. Dryopteris belongs to Pteropsida (ferns); it is generally homosporous, and fertilisation requires water for transfer of biflagellate antherozoids to the archegonium. 4. Equisetum belongs to Sphenopsida; it is a homosporous pteridophyte with strobili at the apex of its shoots. 5. Spirogyra belongs to Chlorophyceae; it reproduces by isogamous fusion of non-motile gametes. How many of the above statements are correct?
