Question

Assertion :We cannot classify Polytrichum under tracheophytes. Reason: Polytrichum belongs to the division pteridophyte and they do not possess vascular tissue. Tracheophytes are vascular-bearing plants.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Both the Assertion and the reason are false
• D. Assertion is false but and Reason is true

Answer 1

The correct option is C Both the Assertion and the reason are false

Tracheophytes are those plants which possess conducting or vascular tissues, i.e. xylem and phloem. Xylem transports water and minerals and phloem conducts organic food.

Polytrichum is a moss which belongs to the division Bryophyta. Bryophytes are non-vascular terrestrial plants of moist habitats in which a multicellular diploid sporophyte lives as a parasite on an independent multicellular haploid gametophyte.Polytrichumdoes not possess vascular tissues, but they possess some water-conducting tissues called hydroids and leptome, which are analogous to xylem and phloem respectively. So polytrichum is said to have a vascular system and it can be classified under tracheophytes, even though it is a bryophyte. So the assertion is false.

Polytrichum belongs to bryophytes and that itself is enough to state that the reason is false.

Since both the assertion and the reason are wrong, option 'C' is the correct option.
