WebThe thick layers of peptidoglycan in the "Gram-positive" cell wall stain purple, while the thin "Gram-negative" cell wall appears pink. By combining morphology and Gram-staining, most bacteria can be classified as belonging to one of four groups (Gram-positive cocci, Gram-positive bacilli, Gram-negative cocci, and Gram-negative bacilli). Web1 answer. Archaea and bacteria are both types of single-celled microorganisms that lack a nucleus and other complex cellular structures. However, there are several important differences between these two types of organisms: 1. Cell wall composition: Archaea have a unique cell wall that is composed of different molecules than those found in ...
