Vedclass · Answer

(D) In a typical angiosperm embryo sac,there are $3$ cells at the chalazal end,which are called antipodals,not $4$. Therefore,statement $A$ is incorrect.$A$ typical mature angiosperm embryo sac consists of $8$ nuclei but only $7$ cells. These include $3$ antipodal cells at the chalazal end,$2$ synergids and $1$ egg cell at the micropylar end (forming the egg apparatus),and $1$ large central cell containing $2$ polar nuclei. Therefore,statement $R$ is correct.

$A$ - Four cells are at the chalazal end and are called the antipodals.
$R$ - $A$ typical angiosperm embryo sac,at maturity,though $8$-nucleate is $7$-celled.
