bacteria. Bacteria that stain purple are considered gram-positive and bacteria that stain pink are considered gram-negative. B. What is the difference between gram-positive and gram-negative cell walls? Gram-positive cell walls are thick and have many interconnecting layers of peptidoglycan. Gram-negative cell walls are thin and have only one layer of peptidoglycans that are two or three layers thick. C. What is the purpose of crystal violet in the Gram’s stain procedure? The crystal violet increases

cell wall synthesis during the stage of active multiplication and is a broad spectrum drug. The organisms that we tested with Amoxicillin, both Gram + & - were all resistant to this drug. The Zone of Inhibition was 0mm for E. Coli, S. Aureus, P. aeruginosa, S. marcescens. 2. Ampicillin’s mode of action is to penetrate Gram + and some Gram – cells. It has an Amino group which helps it to penetrate the outer membrane of Gram- bacteria. It inhibits bacteria from making cell walls and leads

Potential is a measure of potential energy that predicts which way water will move 3. Calculating water potential d. Water potential = pressure potential + solute potential vii. Pressure potential – pressure exerted by the plant cell wall that limits water from moving in viii. Solute potential – the effect of solute concentration. Pure water at atmospheric pressure has a solute potential of zero. As solute is added, the value for solute potential becomes more negative.
