Identify the given figure :

If the number of chromosomes in root cells is $14$, what will be the number of chromosomes in synergids cells of an ovule of that parent

With a neat diagram explain the $7 -$ celled, $8 -$ nucleate nature of the female gametophyte.

$A$- Four cells are at the chalzal end and are called the antipodals.

$R -$ A typical angiosperm embryo sac, at maturity,though $8$-nucleate is $7$-celled

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