Why is bacterial classification important in microbiology?

Bacterial classification helps in identifying, naming, and grouping bacteria, which is crucial for diagnosing diseases, selecting treatments, and studying bacterial roles in health, industry, and the environment.

What is the difference between Gram-positive and Gram-negative bacteria?

Gram-positive bacteria have a thick peptidoglycan cell wall that retains the violet stain, while Gram-negative bacteria have a thin peptidoglycan layer and an outer membrane, appearing pink after staining.

How do bacteria differ based on oxygen requirements?

Some bacteria need oxygen to grow (aerobic), some grow without it (anaerobic), others can survive with or without oxygen (facultative anaerobes), and a few need very little oxygen (microaerophiles).
