Cells are stained then seen through microscopes.
Magnification can be used to see cells more clearly by enlarging the image of the cells, making their details easier to observe. This is achieved by using a microscope with lenses that magnify the image of the cells, allowing for a closer and more detailed view of their structures.
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.
Cells tend to be rather transparent under the microscope, and staining them makes it much easier to see the internal structures.
they are easier to see when you use a microscope
It makes it easier to see where things are and to pick out cells and their references. It is also easier to see the widths of columns and heights of rows, especially when they have been changed.
Stains or dyes are chemicals used to make cells more visible under a microscope by enhancing contrast and highlighting specific structures within the cells.
A stain is a liquid used to make cell structures easier to see by adding color contrast. Stains can highlight specific parts of cells, making them more visible under a microscope. Different stains target different cell components or characteristics.
To make cells easier to see under a microscope, a common chemical used is a stain called "hematoxylin and eosin" (H&E). Hematoxylin stains cell nuclei blue-purple, while eosin stains the cytoplasm and extracellular matrix pink. This staining technique helps researchers and scientists distinguish different structures within cells and tissues.
That is not the reason that they have cell walls but they are easier to see because they do. It is rather like splitting hairs. The first person who described and called cells the name 'cell', looked at cork (a plant). Cellulose forms protective framework for a plant cell to survive. It is a structural carbohydrate used in protection and support. They help a plant keep its shape.
Indeed they are.
