Question

Which among the following are incorrect?

(a) Microsporophylls are spirally arranged to form Strobili to form a cone shaped structures called microsporangiate

(b) Microsporangiate is also called as male strobili because they contain microspores that form male gametophyte

(c) Gametophytes can’t exist independently i.e. free living

(d) Microsporangiate and macrosporangiate exists within the same plant

This question was posed to me in exam.

Question is from Plant Kingdom in division Plant Kingdom of Biology – Class 11

Answer 1

Correct choice is (d) Microsporangiate and macrosporangiate exists within the same plant

Easiest explanation: Sporophylls are spirally arranged to form strobili. Microsporophylls are spirally arranged to form Strobili to form a cone shaped structures called microsporangiate or male strobili. Microsporangiate is also called as male strobili because they contain microspores that form male gametophyte. Gametophytes can’t exist independently i.e. free living. Microsporangiate and macrosporangiate might exists within the same plant or mayn’t.
