Methelyne BLue is a great stain to use for onion cells. It is toxic, however, and in activities that involve young kids it is often substituted.
Staining Elodea and Anabaena cells with methylene blue can be useful in microscopy to enhance contrast and visualize cell structures more clearly. Methylene blue is commonly used as a general stain to highlight cellular components such as nuclei and cytoplasm. This staining technique can aid in identifying cellular organelles and structures during microscopic examination.
Methylene blue can act on only dead yeast cells because it is able to penetrate the cell membrane easier when the cell is dead, allowing it to enter and stain the cell. In live yeast cells, the cell membrane is intact and acts as a barrier, preventing methylene blue from entering and staining the cell.
Because negative staining requires the use of an acidic stain, which will not penetrate the cells because of the negative charge on the surface of the bacteria. As a result, the unstained cells can be easily identified against the colored background.
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 necessary for various applications, such as in medical diagnostics, staining biological tissues, and as a medication to treat methemoglobinemia. It is also used as a redox indicator in chemical reactions and as a dye in various industries. In microscopy, methylene blue can help highlight cell structures for better visualization.
Adding methylene blue to a slide will stain animal cells and make the nuclei more visible.
iodine
One substance that has a similar function as methylene blue is crystal violet. It is commonly used in staining techniques for microbiological studies and exhibits similar properties in terms of staining cells and tissues.
Both are used in staining but for different purposes .
Methylene blue stains everything blue.
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).

Eosin is a red stand and methylene blue is blue. The result of staining a bacterial smear with a mixture of eosin and methylene blue is that eosin is acidic and acts as a negative stain. Methylene blue is basic the smear background would turn out red while the cells would turn out blue.
