Consider the following four statements whether they are correct or wrong. The two wrong statements together are

  1. A and C
  2. A and D
  3. B and C
  4. A and B.

Answer

(2) A and D

Solution

A. As per NCERT, the sporophyte in mosses is more elaborate than that in liverworts. ⇒ Wrong.

B. Salvinia produces microspores and megaspores, i.e. it is heterosporous. ⇒ Correct.

C. In all seed-bearing plants (gymnosperms and angiosperms) the sporophyte is dominant and the gametophyte is reduced, i.e. the life-cycle is diplontic. ⇒ Correct.

D. In Pinus (monoecious) the male and female cones are borne on the same tree. ⇒ Wrong.

∴ The two wrong statements are A and D.
