Read the following five statements (A to E) and select the option with all correct statements.

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

Answer

(1) A, D and E

Solution

A. Correct – lichens (followed by mosses) are pioneer organisms; they are the first to colonise rocks and help in breaking them down for soil formation.

B. Incorrect – Selaginella and Salvinia are heterosporous pteridophytes (they produce megaspores and microspores).

C. Incorrect – the coralloid roots of Cycas are associated with N2-fixing cyanobacteria; VAM (mycorrhiza) is found in the roots of Pinus.

D. Correct – the main plant body of a bryophyte is the haploid gametophyte, while in pteridophytes it is the diploid sporophyte.

E. Correct – as per NCERT, in gymnosperms the male and female gametophytes remain within the sporangia retained on the sporophytes.

∴ A, D and E are correct.
