Match the following:
| Bacterial (Based on morphology) | Properties (Shape) |
|---|---|
| a. Cocci | 1. Rod shaped |
| b. Bacilli | 2. Coma shaped |
| c. Vibrio | 3. Spiral shape having coils |
| d. Spirochaetes | 4. Spherical or oval |
Choose the most appropriate option from below :
Answer: D
The correct matching is a-4, b-1, c-2, d-3.
- Cocci are spherical or oval.
- Bacilli are rod shaped.
- Vibrio are curved, comma shaped rods, like Vibrio cholerae.
- Spirochaetes are thin, flexible spirals with coils, like Treponema pallidum.
The other codes fail on the simplest pair: coccus comes from the Greek for a berry or seed, so cocci can only be the spherical form, and only option D gives them that.
