Question : Which cell organelle appears as rounded or sausage-shaped structures under electron microscopy, measuring about 0.5-1.0 μm in diameter and 2-8 μm in length?
Option 1: Ribosomes
Option 2: Lysosomes
Option 3: Mitochondria
Option 4: Plastids
Correct Answer: Mitochondria
Solution : The correct answer is Mitochondria.
The cell organelle that appears as rounded or sausage-shaped structures under electron microscopy, measuring about 0.5–1.0 μm in diameter and 2–8 μm in length, is the mitochondrion. Mitochondria are responsible for energy production within the cell through the process of cellular respiration.
