Question

Which of the following matches is correct regarding the shape of bacteria?

• A. Coccus - rod-shaped
• B. Bacillus - comma-shaped
• C. Spirillum - spiral
• D. Vibrio - spherical

Hint:

Remember the common bacterial shapes: \[ \boxed{\text{Coccus} \rightarrow \text{Spherical}} \] \[ \boxed{\text{Bacillus} \rightarrow \text{Rod-shaped}} \] \[ \boxed{\text{Vibrio} \rightarrow \text{Comma-shaped}} \] \[ \boxed{\text{Spirillum} \rightarrow \text{Spiral-shaped}} \] These four bacterial shapes are frequently asked in biology examinations.

Answer 1

The Correct Option is C

Bacteria are classified by shape: coccus (spherical, e.g., Staphylococcus), bacillus (rod-shaped, e.g., Escherichia coli), spirillum (rigid spiral, e.g., Spirillum), and vibrio (comma-shaped, e.g., Vibrio cholerae). These morphological categories are a primary basis for identifying bacterial genera.
