Vedclass · Answer

(C) $Araucaria$ is a genus of evergreen coniferous trees in the family $Araucariaceae$. Statement $A$ is true: The scale leaves of $Araucaria$ are indeed small,brown,and often appressed to the stem. Statement $R$ is false: $Araucaria$ is a gymnosperm. In gymnosperms,the sporophytic phase is dominant,long-lived,and independent. The gametophytic phase is highly reduced,dependent on the sporophyte,and is not subterranean. The description of a long-lived,subterranean gametophyte is characteristic of certain pteridophytes (like $Lycopodium$),not gymnosperms like $Araucaria$.

$A$: The scale leaves of $Araucaria$ are small and brown.
$R$: The gametophytic phase of $Araucaria$ is long-lived and subterranean.
