Expert Solution & Answer

Explanation of Solution

Proper care should be taken while preparing a smear for microscopic examination. The advantages of preparing thin smears are as follows:

1. Thin smears permit easy passage of light, which gives better resolution of bacteria, particularly when using oil immersion.

2. Dense or thick smears will lead to uneven spread of bacteria in the microscopic slide.

3. In the case of dense smears, stains are unable to penetrate the bacterial cell wall.
