• 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

Answer 1

Answer:

D. Microsporangiate and macrosporangiate exists within the same plant

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.
