Methylene blue is a stain(dye). Dyes are specific to the substance and bind only to that specific substance. Methylene blue is specific to animal cells and hence is used to observe animal cells.
Different stains are used for different materials, based on their pH value. High pH values are better against low pH values, and methylene blue is alkaline (meaning high pH), so using it on a cell reveals the more acidic parts (like the nucleus) while leaving the more alkaline parts (like the cytoplasm) undyed.
It makes it easier to see whatever your studying. I have a microscope myself, and tried to study a flies wing without using dye and a slide, and it was harder to make out. By the way, ants look really cool under a microscope.

Because the cells are transparent, and they cannot be seen through a microscope without dye to make them visible to the human eye.
Stains can help you differentiate cellular content. without a stain, it's hard to tell the difference between some of the structures of a cell.
cells are more visible
nuclei in animal cells
Methylene blue stain is used to stain plant and animal cells.
Methylene Blue, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.
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

iodine
Methylene Blue is the name of the dye Iodine is used for dyeing plant cells hope this helps :-)

Both are used in staining but for different purposes .

Methylene blue is used for many different staining purposes, but one of the main ones is staining RNA or DNA. In animal cells, it will stain the cytoplasm and the nucleus (the nucleus will be much darker).

Methylene blue is an example.
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
