The Gram staining method is named after the Danish bacteriologist who originally developed it in 1882‚ Hans Christian Gram. The Gram staining process is one of the most important staining techniques in microbiology. It is almost always the first test performed for the identification of bacteria. The primary stain of the Gram’s method is either crystal violet or methylene blue‚ each almost equally effective. The microorganisms that retain the crystal violet and iodine mixture appear purplish brown

What is the difference between ecosystem and ecology? Ecosystem is the physical system (an open system) in which the mutual interaction between biotic and aboitic component motored by the energy component is studied. While the Ecology is the science which study the interrelation between Abiotic (inorganic) and Biotic (organic) components as well as the interaction among the biotic component. To make it more clear‚ ecosystem is the fundamental unit of ecological study. Ecology vs Ecosystem
