During a gram stain some bacteria retains the stain because they are gram positive with thicker walls . If the bacteria does not stain either it is an endospore bacteria or gram negative with thinner walls, so colorless or red color.

∙ 14y agoBiologist group most species of bacteria into two categories based on structures of their cell walls. Gram-negative bacteria have cells walls that are complex and and have small amount of peptidoglycan. Gram-negative bacteria take up the second, red dye of the Gram stain process which makes the cells appear reddish pink. Gram-positive bacteria are simpler and have much more peptidoglycan which retains the purple in their cell walls and appear purple.

∙ 11y agoSome bacteria test Gram positive because they have a thick cell wall made up of peptidoglycan that traps the crystal violet in the cytoplasm. Others test Gram negative because they have a thinner layer of peptidoglycan and crystal violet is easily rinsed from the cytoplasm.

∙ 10y agoGram-positive bacteria have a cell wall consisting of a plasma membrane, periplasmic space, and a peptidoglycan layer.
Gram-negative bacteria have the same cell wall structures as gram-positive bacteria. However, they have an additional periplasmic space and outer membrane made of lipopolysaccharide and protein.

negative!
What functions do amoxicillin have?
Amoxicillin is for penicillin class of antibiotics. By inhibiting the synthesis of bacterial cell walls, it makes the bacteria expanding and cracking to take sterilization effects. It has good antibacterial activity for the hemolytic streptococcus, pneumonia streptococcus, penicillin enzyme aureus, dung enterococcus, singular proteus and other aerobic gramnegative bacteria and so on. Amoxicillin sodium for injection is suitable for a variety of infections caused by sensitive bacteria for the heavy patients requiring hospitalization or not being able to take by mouth. See related link for more info.
