Vedclass · Answer

(B) The correct answer is $B$. $1$. $Ginkgo$ is a gymnosperm,and gymnosperms produce archegonia in their female gametophyte. This is correctly matched. $2$. $Salvinia$ is a heterosporous pteridophyte. Pteridophytes produce a prothallus,but heterosporous pteridophytes like $Salvinia$ produce reduced gametophytes that do not form a typical independent prothallus structure. Thus,this is wrongly matched. $3$. $Viroids$ are infectious agents consisting only of a short strand of circular single-stranded $RNA$. This is correctly matched. $4$. $Mustard$ is an angiosperm. In angiosperms,the embryo sac contains synergids. This is correctly matched.
