Next Plants require several different chemical elements in order to thrive. Oxygen, carbon and hydrogen are found in water and air; secondary nutrients that plants need include magnesium, calcium and sulfur.
Quick Review Chemical growth requirements of microbes To grow successfully, microorganisms must have a supply of water as well as numerous other chemical substances.
Unlike the physical requirements where a specific range or concentration is necessary for optimum growth, the chemical requirements just need to be present Chemical growth the environment and a microbe will use what it needs. Microbes use compounds containing the following elements and vitamins to make everything in the cell including membranes, proteins, and nucleic acids: Energy All living organisms require a source of energy.
Carbon can be obtained from organic materials in the environment, or it may be derived from carbon dioxide. A notable example is the nitrogen fixation enzyme nitrogenase, which is very oxygen sensitive. Nitrogen, sulfur, and phosphorus Among the other elements required by microorganisms are nitrogen and phosphorous.
Most microbes get these elements by degrading proteins and nucleic acids. Trace elements,vitamins and amino acids Trace elements such as iron, copper, molybdenum, and zinc are needed as cofactors for enzymes and must be obtained, in tiny amounts, from the environment.
Unlike humans, microbes can make vitamins, which also act as enzyme cofactors. Some microbes, however, lack the ability to make one or several vitamins and have to get them from their environment.3.
chemical inhibitors — this type of barrier is a textile that is impregnated or covered with a chemical root growth inhibitor. One commonly used chemical is cupric carbonate (CuCO3).
Another widely used chemical root inhibitor is trifluralin, an herbicide that inhibits root tip expansion.
