because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
It bleaches and becomes clear

When you added methylene blue to the living yeast cell, the methylene blue is actually a dye so you could see the cells, therefore, the yeast cell became blue. It is much the same with hair dye. If you have a bottle of blue hair dye, it will dye your hair blue.
Methylene blue is helpful to observe cells through a violet-blue color, making organelles, as well as the cell, easier to identify.
When methylene blue stains a tomato cell, it stains both the nucleus and the cytoplasm of the eukaryotic cells. These are the most important organelles of a plant.?æ
Methylene blue is used to stain animal cells, such as human cheek cells, to make their nuclei more observable. Also used to staining the blood film and used in cytology. It gives a blue coloration to the human cheek cell.
because the nuclear bytrate in the animal cell does not react with methylene blue

Methylene blue is a solid, odorless, dark green powder at room temperature. In water this chemical compound turns into a blue solution. When methylene blue is reacted with yeast cells it inhibits the respiration which stops the cells from using hydrogen ions to release energy.

Methylene blue is a membrane-permeable dye that can enter the cell and bind to cellular components, such as proteins and nucleic acids. This binding can alter the osmotic properties of the cell and affect its solute potential. Methylene blue can also disrupt the electron transport chain in mitochondria, leading to changes in cellular metabolism and solute potential.
