Mark the incorrect statement.

Which one of the following is a vital stain?

Match column $I$ (cell type) with column $II$ (size) and choose the correct option.

Column-$I$ (Cell type)	Column-$II$ (Size)
$A$. Viruses	$I$. $1-2 \; \mu m$
$B$. $PPLO$	$II$. $10-20 \; \mu m$
$C$. Eukaryotic cell	$III$. About $0.1 \; \mu m$
$D$. Bacterium	$IV$. $0.02-0.2 \; \mu m$

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Endoplasmic Reticulum	$(P)$ Provides energy for various cell functions
$(2)$ Golgi apparatus	$(Q)$ Involved in the formation of basal bodies
$(3)$ Chloroplast	$(R)$ Surrounded by a single membrane
$(4)$ Mitochondria	$(S)$ Site of synthesis of glycolipids and glycoproteins
$(5)$ Lysosomes	$(T)$ Performs photosynthesis
$(6)$ Centriole	$(U)$ Synthesis of lipids

Which of the following statements are correct?
$I$. $PPLO$ is the smallest cell.
$II$. Prokaryotic cells are smaller than eukaryotic cells.
$III$. Cell division in prokaryotic cells is slow.
$IV$. All bacteria show solitary and colonial forms.
$V$. Cell division in prokaryotic cells is very rapid.
