Identify the correct statements w.r.t. the given cell diagram:
$A$. Concerned with lipid and steroidal hormone synthesis.
$B$. Outer non-living rigid structure which gives shape to the cell and protects from mechanical damage and infection.
$C$. Both lie perpendicular to each other and each has an organisation like the cart wheel.
$D$. Responsible for trapping light energy for the synthesis of sugar.
$E$. Present in cells actively involved in protein synthesis and secretion.
$F$. Spherical structures,rich in hydrolytic enzymes.

$A$: All organelles in a eukaryotic cell are membrane-bound.
$R$: Organelles in a prokaryotic cell are membrane-less.
