Question

for what reason do we need to stain bacteria ??

Answer 1

Answer:

Microbiologists study the characteristics of microorganisms such as algae, protozoa, bacteria, fungi and viruses using a microscope. While some organisms such as protozoa and yeast cells are easy to observe using a wet mount, bacterial cells require staining. Scientists developed several methods such as Gram staining, acid-fast staining and fluorescent staining for better visualization of bacterial cells and cellular structures. Using such staining methods, it is possible to identify structural features that help classify bacteria.
