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?
View solution & NCERT explanation
Correct answer: C — 1, 2, 3, 4 and 5
Statement 1 → Correct: Chara is a green alga (Chlorophyceae), reproduces oogamously. Statement 2 → Correct: Selaginella (Lycopsida, pteridophyte) is heterosporous, produces megaspores + microspores in strobili. Statement 3 → Correct: Dryopteris (fern, Pteropsida) is generally homosporous; requires water for antherozoid movement. Statement 4 → Correct: Equisetum (Sphenopsida) is homosporous and forms strobili. Statement 5 → Correct: Spirogyra (Chlorophyceae) reproduces by isogamous fusion of non-motile gametes. Thus, all 5 statements are correct.
