Vedclass · Answer

(A) In Crucifer-type (or Onagrad-type) embryo development,the zygote divides to form a terminal cell and a basal cell.The terminal cell forms the octant embryo,which differentiates into the plumule and the hypocotyl.The basal cell forms the suspensor,and the cell of the suspensor adjacent to the embryo proper is called the hypophysis.The hypophysis undergoes divisions to form the root cap and the tip of the radicle.Therefore,the hypo-basal tier of the octant embryo does not produce the complete radicle,as the tip is derived from the hypophysis.Both statements are correct and the Reason explains why the hypo-basal tier does not produce the complete radicle.

$A$: Complete radicle is not produced by the hypo-basal tier of the octant embryo during Crucifer-type development.
$R$: The hypophysis cell of the suspensor contributes to the tip of the radicle in this type of development.
