Bacteria are a huge group of single-celled microscopic organisms categorized as prokaryotic cells (lack true nucleus). Their inner structure is simple composing mainly of capsule, cellular wall, cytoplasm, ribosomes, DNA, pili, and flagellum. Bacteria can either be a gram-positive or gram-negative, and to find it out, a gram-staining technique has to be used.
Gram Staining technique is the most important and widely used microbiological differential staining technique. It categorizes bacteria according to their Gram character (Gram positive or Gram negative).
Along with their staining characteristics, Gram Positive and Gram Negative bacteria differ from each other in various aspects which are listed below :
