(N/A) $\rightarrow$ $Cycas$ is considered a 'relic of the past' because it is an evergreen plant that resembles a palm tree. It possesses unbranched stems and large compound leaves. It shows specific developmental relationships with $Pteridophytes$. Its evolutionary characteristics that justify this are as follows:
$(i)$ Slow growth.
$(ii)$ Shedding of seeds while the embryo is still underdeveloped.
$(iii)$ Less primary growth and $Monoxylic$ wood.
$(iv)$ Leaf-like $Megasporophylls$.
$(v)$ Presence of flagellated (motile) male gametes,even though a pollen tube is present.
$(vi)$ Persistent nature.
$(vii)$ $Circinate$ $ptychis$ (coiling of young leaves) similar to ferns.
$(viii)$ The arrangement of microspores is primitive.
