Question

Match the following (Cell type vs Size).

• A. A-IV, B-I, C-II, D-III
• B. A-IV, B-I, C-III, D-II
• C. A-IV, B-III, C-II, D-I
• D. A-I, B-IV, C-III, D-II

Hint:

PPLO is the smallest known cellular organism (\(\approx 0.1\mu m\)). Human RBC diameter is approximately \(7\mu m\).

Answer 1

The Correct Option is B

Step 1: Recall standard cell sizes.
\[ \text{PPLO} \approx 0.1\ \mu m \] \[ \text{Bacteria} \approx 1-2\ \mu m \] \[ \text{Human RBC} \approx 7\ \mu m \] \[ \text{Typical eukaryotic cell} \approx 10-20\ \mu m \]

Step 2: Match correctly.
\[ A \rightarrow IV \] \[ B \rightarrow I \] \[ C \rightarrow III \] \[ D \rightarrow II \] Therefore: \[ \boxed{\text{A-IV, B-I, C-III, D-II}} \]
