Vedclass · Answer

(D) The genus $Gnetum$ is unique among gymnosperms because it exhibits several characteristics that are typically found in angiosperms. $1$. The presence of vessel elements in the xylem is a key feature of angiosperms,which is also found in $Gnetum$ but absent in $Cycas$ and $Pinus$. $2$. The absence of archegonia in the female gametophyte of $Gnetum$ is another significant trait that aligns it with angiosperms,whereas $Cycas$ and $Pinus$ possess archegonia. Therefore,the presence of vessel elements and the absence of archegonia are the defining features that distinguish $Gnetum$ from other gymnosperms and show its evolutionary affinity with angiosperms.

Select the pair of features that distinguishes $Gnetum$ from $Cycas$ and $Pinus$ and shows affinities with angiosperms.
