Vedclass · Answer

(B) $Gnetum$ is a unique gymnosperm that exhibits several characteristics similar to angiosperms,which are not found in other gymnosperms like $Cycas$ and $Pinus$. $1$. The most significant feature is the presence of vessel elements in the xylem,which is a characteristic trait of angiosperms. $2$. Additionally,$Gnetum$ lacks archegonia in its female gametophyte,a feature that aligns it more closely with the reproductive structure of angiosperms. $3$. Therefore,the presence of vessel elements and the absence of archegonia are the key features that distinguish $Gnetum$ from other gymnosperms and suggest an evolutionary link to angiosperms.

Select the feature that distinguishes $Gnetum$ from $Cycas$ and $Pinus$ and shows affinities with angiosperms.
