Answer:
C.Both Gram positive and Gram negative cells would appear purple.
Explanation:
Gram staining is a technique used to differentiate bacteria to two main groups based on their difference in cell wall components.
Crystal violet, decolorizer(ethanol) and a counter stain are used.
Gram positive bacteria have a thicker peptidoglycan layer hence they will retain the crystal Violet stain even after decolorization. They will stain purple
Gram negative will stain pink due to losing the initial stain and taking up the counter stain after decolorization.
Therefore, if water is used instead of ethanol. Both bacteria will retain crystal violet stain in their cell wall.
