GENERAL HISTOLOGY

Detailed explanation-1: -Methylene blue is used to impart a blue colour to cheek cells. This makes them easily observable under a microscope.

Detailed explanation-2: -Methylene blue is used in gram staining. Gram staining is one of the most important staining methods in microbiology. The predominant colour in gram staining is methylene blue. Gram-positive organisms are organisms that preserve the primary colour and look purple-brown under a microscope.

Detailed explanation-3: -The methylene blue stain makes nuclei more visible although it stains both nuclei and cytoplasm; the eosin mainly colors the cytoplasm and cell membranes.

Detailed explanation-4: -Methylene blue stain is a simple stain where a single dye is used to emphasize particular structures in the sample, shape (the size and arrangement of bacteria). The organisms in a sample will be the same color, even if the sample contains more than one type of organism.

Detailed explanation-5: -This makes them easily observable under a microscope. It imparts a characteristic pink colour to the cells. Methylene blue is used to impart a blue colour to cheek cells.
