Question

Read the following statements (A– E) and answer the question which follows them :

(A) In liverworts, mosses and ferns gametophytes are free-living

(B) Gymnosperms and some ferns are heterosporous

(C) Sexual reproduction in Fucus, Volvox and Albugo is oogameous

(D) The sporophytes in liverworts is more elaborate than that in mosses

(E) Both, Pinus and Marchentia are dioecious

How many of the above statements are correct ?

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is C Three

Statement A, B and C are correct.

Gametophytes of liverworts, mosses, and ferns are independent and so are free-living. Gymnosperms and some ferns are heterosporous, meaning that they have two different types of spores.

Sexual reproduction in Fucus, Volvox and Albugo is oogamous meaning they have small flagellated male gamete and large non-flagellated female gamete.

The sporophyte of moss is more elaborate than the liverworts.

Pinus is monoecious while Marchantia is dioecious.

Thus, the correct answer is the option (C), 'Three'.
