Question

gram staining
the light red dye, safranin, then gets added. gram - positive bacteria will be colored purple since they have both stains in their cell walls. gram - negative bacteria however, will only take the pink color from safranin.
what does crystal violet do?
dyes cells pink
decolorizes the cells
dyes cells purple

Explanation:

In Gram - staining, crystal violet is the primary stain that dyes bacteria purple. It binds to the peptidoglycan layer in the cell wall of bacteria. After crystal violet application, iodine is added as a mordant to form a crystal - violet iodine complex. Gram - positive bacteria retain this purple - colored complex due to their thick peptidoglycan layer, while Gram - negative bacteria are decolorized later and then take up the counter - stain (safranin) to appear pink.

Answer:

dyes cells purple
