Explanation:
Detailed explanation-1: -The bacteria need to be firmly attached to the slide so they are not washed off during the staining procedures.
Detailed explanation-2: -Allow the smear to air dry completely. 6. Fix the smear to the slide using heat fixation or methanol fixation according to your laboratory’s procedure. 7.
Detailed explanation-3: -Why Stain Cells? The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.
