Select the correct option that matches the cell organelle with its function:

Cell Organelle	Function
$(A)$ Endoplasmic Reticulum	$(i)$ Powerhouse of the cell
$(B)$ Free Ribosomes	$(ii)$ Involved in osmoregulation and excretion
$(C)$ Mitochondria	$(iii)$ Lipid synthesis
$(D)$ Contractile Vacuole	$(iv)$ Protein synthesis

$A$ student wants to study cell structure using a light microscope with a $10 \times$ eyepiece and a $45 \times$ objective lens. Which of the following light sources should they use to obtain the best resolution?

In the given hierarchy of biological organization: $(P) \rightarrow \text{Subatomic particles} \rightarrow \text{Atoms} \rightarrow \text{Molecules} \rightarrow (Q) \rightarrow \text{Cells} \rightarrow \text{Tissues}$,what do $(P)$ and $(Q)$ represent respectively?

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.

Which of the following organelles contain ribosomes?

The following diagram shows a plant cell with some structures marked as $A, B, C, D$ and $E$. Choose the option with their correct names.
