Multiple stains can be simultaneously used on a tissue, such that different cell types appear in different colors. Methylene blue staining can be used for cheek cells. Disadvantages: (1) It causes marked shrinkage of cells (this may be counteracted by addition of acid) (2) It rapidly hardens the outer layer of the tissue with incomplete fixation of the center, therefore, thinsections should be made. These are members of the prokaryote kingdom. Infections caused by bacteria should not be ignored even the symptoms are just mild, and one of the most commonly used methods to do this and find some treatments to address severity and spread is Gram staining. They give the image more contrast and allow cells to be classified according to their shape (morphology). See full answer below. 8 What are the advantages of using Gram stain? What is thought to influence the overproduction and pruning of synapses in the brain quizlet? Before bacteria can be stained, a smear of bacteria must be made on a slide and heat fixed.
