Shape of Staphylococcus bacteria is

Options

A. Circular
B. Oval
C. Elongated
D. Cubical.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the shape of Staphylococcus bacteria.

2. **Microscopic Observation**: When viewed under a microscope, Staphylococcus bacteria appear as small colonies that have a smooth and glossy surface.

3. **Non-Motility**: Staphylococcus bacteria are non-motile, meaning they do not have structures like cilia or flagella for movement.

4. **Shape Identification**: Staphylococcus bacteria are classified as spherical-shaped bacteria, known as cocci.

5. **Cluster Formation**: Unlike other cocci that may exist as single cells or in pairs, Staphylococcus bacteria tend to form clusters. This clustering resembles grape-like structures.

6. **Division in Multiple Planes**: The clustering occurs because the bacteria divide in more than one plane, leading to a three-dimensional arrangement.

7. **Conclusion**: Therefore, the shape of Staphylococcus bacteria is circular (spherical).

8. **Final Answer**: The correct answer to the question is that Staphylococcus bacteria are circular in shape.
