Vedclass · Answer

(A) In the family $Fabaceae$,the flower exhibits vexillary aestivation.This arrangement consists of five petals: one posterior standard (vexillum),two lateral wings (alae),and two anterior petals forming a keel (carina).The standard petal is the largest and overlaps the two lateral wings (alae),which in turn overlap the two smallest anterior petals (keel).Therefore,the assertion that there are two alae is correct,and the reason that they are covered by the largest petal (standard) is also correct and explains the structural arrangement.

$A$ : There are two alae in $Pisum$ $sativum$ flower.
$R$ : Both alae are covered by the largest petal.
