(b) Gymnosperms and some ferns and some ferns are heterosperms and some ferns are heterosporous
(c) Sexual reproduction in Fucus,Volvox and Albugo is oogamous
(d) The sporophyte in liverworts is more elaborate than that in mosses

Correct Answer:

Gymnosperms and some ferns and some ferns are heterosperms and some ferns are heterosporous

Explanation:

Oogamous is a type of sexual reproduction in which the fusing gametes are dissimilar.One of the gametes is smaller and it behaves as the male gamete.The larger non- motile gamete acts as a female gamete. The system of reproduction between the dissimilar gametes is known as the oogamy; it is a type of heterogamy. This type of reproduction is common in red algae and brown algae; it is also present in the green algae.
