    2011 Plants and Nitrogen Lab Report Introduction: Plants need ammonia‚ a combination of nitrogen and hydrogen‚ or nitrate‚ a form of inorganic nitrogen to grow. Most nitrogen is found in the atmosphere. However‚ plants and animals cannot directly absorb the nitrogen found in the atmosphere. Instead nitrogen gas is captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The

    mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating
