Vedclass · Answer

(A) In dicot embryogeny,the zygote undergoes a transverse division to form a terminal cell (embryonal cell) and a basal cell.The terminal cell undergoes two vertical divisions at right angles to each other,followed by one transverse division,resulting in an eight-celled stage known as the octant stage.These eight cells are arranged in two tiers: the upper four cells form the epibasal tier (which gives rise to plumule and cotyledons),and the lower four cells form the hypobasal tier (which gives rise to the hypocotyl and radicle).Thus,both the Assertion and the Reason are correct,and the Reason correctly explains the arrangement of the cells formed in the octant stage.

$A$: Eight cells of the octant stage in dicot embryogeny are formed by $2$ vertical and $1$ transverse division in the embryonal cell.
$R$: These cells are arranged in epibasal and hypobasal tiers.
