NEET 2020 · BiologyPteridophytesPrevious Year Question
Strobili or cones are found in:
Answer: (B) Equisetum. Answer: (B) Equisetum.
- A.Marchantia
- B.Equisetum✓
- C.Salvinia
- D.Pteris
Correct Answer
(B) Equisetum
Solution & Explanation
Answer: (B) Equisetum. Solution: In some pteridophytes the sporophylls aggregate into distinct compact structures called strobili or cones; NCERT names Selaginella and Equisetum as examples. Equisetum is the correct choice here. Marchantia is a bryophyte (liverwort) that bears no strobili; Salvinia and Pteris are pteridophytes but do not form cone-like strobili. (Answer taken from the official NEET 2020 key as no biology key was printed in this paper.) NCERT Reference: Class XI Biology, Plant Kingdom, p.30, lines 41-42 — "In some cases sporophylls may form distinct compact structures called strobili or cones (Selaginella, Equisetum).".
