Identify the correct sequence of events in the life cycle of a flowering plant.

Which of the following statements are true?
$P = \text{Papaver}$ has a multicarpellary syncarpous pistil.
$Q = \text{Endothecium}$ provides nourishment to the Microspore Mother Cell.
$R = \text{Commelina}$ has chasmogamous and cleistogamous flowers.

$A$: Formation of a mature male gametophyte requires one meiotic and two mitotic divisions in $60\%$ of angiosperms.
$R$: Pollination occurs in a two-celled condition in the majority of angiosperms.

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.

Choose the correct option with respect to the type of division during gamete formation and the type of division in the zygote for organisms having a haplontic life cycle,respectively.
