Introduction
This is kidney cell unstained
This kidney cell has been stained with methyl-red.
Let's have a look at cell basics: staining cells, sectioning, surface area
to volume ratio, structures and functions and multicellular organisms.
Many of the structures in cells are difficult to see because they are
transparent or they blend into the background. To make these structures
easier to see with a light microscope scientists often add a liquid stain
to the specimen.
Compare the pictures on this page - one of the cells is stained, the other
is not.

what are the stains used made of?
What structures are identifiable in the cell? Nucleos and mithocondrias. Cytoplasm streaming also called cyclose is the movement of protoplasm within a cell . How can we identify cytoplasm in the cell? Cistoplasm is inside the cell, limited by the cell membrane. Define citoplasm: Cytoplasm is the fluid that fills a cell. Scientists used to call the fluid protoplasm.
