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

Match the items in Column-$I$ with Column-$II$ and select the correct option:

Column-$I$	Column-$II$
$(A)$ Typical animal cell	$(i)$ Multinucleate
$(B)$ Zygote	$(ii)$ Uninucleate
$(C)$ Human $RBC$	$(iii)$ Binucleate
$(D)$ Plant endosperm	$(iv)$ Enucleated

Adult human $RBCs$ are enucleate. Which of the following statement$(s)$ is/are most appropriate explanation for this feature?
$(1)$ They do not need to reproduce.
$(2)$ They are somatic cells.
$(3)$ They do not metabolise.
$(4)$ All their internal space is available for oxygen transport.

Identify the labels $A, B, C, D$ and $E$ in the given diagram. The following components are listed:
$(i)$ $SER$
$(ii)$ Ribosome
$(iii)$ Nucleus
$(iv)$ Nuclear pore
$(v)$ $RER$

Which microscope is used to study the dynamic type of cells?

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.
