For the formation of $140$ angiospermic seeds,how many meiotic cell divisions are expected?

Through which route does the pollen tube enter the ovule?

Match the following:

Column-$I$	Column-$II$
$(1)$ Germ pore	$(a)$ Lack of sporopollenin
$(2)$ Parthenium	$(b)$ Malva
$(3)$ Self incompatibility	$(c)$ Palms
	$(d)$ Contaminant with imported wheat

Choose the correct option from the following statements.
$I$. During embryogenesis,the zygote undergoes mitotic cell division.
$II$. In organisms with a diplontic life cycle,the zygote divides by meiotic cell division.
$III$. The pericarp (fruit wall) develops from the ovary wall after fertilization.
$IV$. In brinjal,sepals remain attached to the fruit even after fertilization.

In $Agave$ (Century plant),vegetative propagation occurs through which of the following?

Match the following columns:

Column-$I$ (Pre-fertilization)	Column-$II$ (Post-fertilization)
$P$. Ovule	$I$. Fruit
$Q$. Integument	$II$. Embryo
$R$. Ovary	$III$. Seed
$S$. Ovary wall	$IV$. Pericarp
$T$. Zygote	$V$. Seed coat
