Tissues arranged together make up organs, which, when functioning together in groups, make up organ systems. This statement refers to the levels of the organization of life in organisms. Tissues came originally from cells, which are the building blocks of life and is the main composition of all living organisms. Both plants and animals have tissues that serve different functions to maintain homeostasis within its respective bodies. Organ systems are developed when organs work together in perfect balance to perform multiple chemical and physical processes within the body. If one organ does not function well it may affect how the other function as well.
For staining flagella of bacteria use actively motile organisms 20 to 24 hours old, allow to diffuse in sterile water 20 to 30 minutes, transfer droplets of the suspension to clean slides and let evaporate without spreading. Then treat 2 to 4 minutes with the following mordant: tannic acid 10 or 20%, 50 cc.; ferric chloride 5%, 10 to 15 cc.; carbol fuchsin (Ziehl-Nielson), 5 cc.; hydrogen peroxide 3%, 6 to 8 cc. Wash and stain 2 to 3 minutes with a mixture of basic fuchsin, saturated alcoholic, 10 cc.; anilin oil (1 part) and 95% alcohol (3 parts) mixed, 5 cc.; distilled water, 30 cc.; acetic acid, 4%, 1 cc.
