Question

Read the given statements and select the incorrect ones.
(i) Sporophyte in mosses is more elaborate than that in liverworts.
(ii) Salvinia is homosporous.
(iii) Life-cycle in all spermatophytes is diplontic.
(iv) In Cycas, male cones and megasporophylls are borne on the same trees.

• A. (i) and (ii)
• B. (i) and (iii)
• C. (ii) and (iv)
• D. (iii) and (iv)

Answer 1

The correct option is C (ii) and (iv)

Few pteridophytes are heterosporous, i.e., with two types of spores, microspores and megaspores, e.g., Selagineiia, Salvinia, Marsilea. Plants of Cycas are also heterosporic and invariably dioecious, i.e., male and'female reproductive organs occur on separate individuals.

So the correct option is C.
