Pick up the bacteria with exceptional shape:
Correct answer: A. Square
- A. Square
- B. Vibrio
- C. Spirillum
- D. Spirochete
Explanation
Square-shaped bacteria are not commonly found in nature and are considered exceptional in bacterial morphology. Bacteria with a square shape are not commonly observed in nature. Most bacteria are characterized by shapes such as cocci (spherical), bacilli (rod-shaped), or spirilla (spiral-shaped). Square bacteria would be an exceptional and unusual morphology.
