gram +ve bacteria's are sphericl/cocci in shape, which has
outer phospolipid layer and lower is peptidogycan layer
which consist of nicotinamide diphosphate and nicotinamide
sulphate chain which are linked by weak glycopeptide bond
due to which when gram staining is performed it retain
methylene blue dye while not that counter(saffranin)stain
which is wash due to alcohol and appear violet/purple in
colour.

while in case of gram -ve are rod shape they appear pink in
colour,since retain counter stain and while addition of
alcohol they shrink out ,capture counter stain,also
composed of outer peptidiglycan and inner phospholipid
layer.
