Vedclass · Answer

(A) In the mature embryo sac,the synergids are characterized by the presence of a large vacuole at the chalazal end and a filiform apparatus at the micropylar end.This specific arrangement of organelles and vacuoles creates a distinct polarity within the synergid cell.The egg cell,conversely,has a large vacuole at the micropylar end and the nucleus at the chalazal end.Therefore,the polarity of the synergid cytoplasm is indeed opposite to that of the egg cell.Both the Assertion and the Reason are correct,and the Reason explains why the synergid has a specific polarity.

$A$: Chalazal vacuole is present in the synergid cell of the embryo sac.
$R$: Polarity of synergid cytoplasm is opposite to the egg cell.
