What is common in all the three, Funaria, Dryopteris and Ginkgo?
- Presence of archegonia
- Well developed vascular tissues
- Independent gametophyte
- Independent sporophyte
Answer
(1) Presence of archegonia
Solution
Funaria is a moss (bryophyte), Dryopteris is a fern (pteridophyte) and Ginkgo is a gymnosperm.
⇒ As per NCERT, the female sex organ archegonium is present in bryophytes, pteridophytes and gymnosperms (archegoniates).
∵ Bryophytes lack vascular tissues and have a dependent sporophyte, while gymnosperms have a dependent (reduced) gametophyte, options (2), (3) and (4) are not common to all three.
