$(II)$ Mitochondrion - 'Power house' of the cell
$(III)$ Stroma - Chlorophyll pigment
$(IV)$ Axoneme $- 9+2$ array

Which of the following is an incorrect pair?

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.

$C$. Eukaryotic cell	$III$. About $0.1 \; \mu m$
$D$. Bacterium	$IV$. $0.02-0.2 \; \mu m$

Match List-$I$ with List-$II$.

List-$I$	List-$II$
$A$. Cristae	$I$. Flat membrane sacs in stroma of chloroplast
$B$. Cisternae	$II$. Infoldings in mitochondria
$C$. Thylakoids	$III$. Cell membrane
$D$. Phospholipid	$IV$. Disc shaped sacs in the Golgi apparatus
