    In addition to Blacksnow's comments, I would add that

    gram negatives can realease endotoxins from their outer membrane and can cause toxic shock syndrome in humans

    GC base contents of DNA are usually higher in gram positives

    because of their difference in the cell wall compositions and strucutre they are susceptible to different antibiotics. for example gram positives are susceptible to penicillin whereas gram negative are not

    they use different communication systems: gram positives use peptides (amino acid chain) to communicate with each other and other species whereas gram negatives use small molecules called homoserine lactones

    hope these helps

    GRAM-POSITIVE are those that retain a crystal violet dye during the Gram stain process

    GRAM-NEGATIVE bacteria appear red or pink.

    In Gram-negative bacteria, the S-layer is directly attached to the outer membrane. In Gram-positive bacteria, the S-layer is attached to the peptidoglycan layer

    that's all i can think of...

    Gram positive bacteria has a thick cell wall with multiple layers of peptidylglycan while gram negative bacteria has a thin cell wall with a few layers of peptidyglycan.

    Gram positive bacteria has no outer membrane but gram negative bacteria has a outer membrane of lipopolysaccharide (LPS).

    Gram positive bacteria will be stained purple with crystal violet while gram negative bacteria will be stained pink with safranin red.
