Chemotaxis is the phenomenon in which bodily cells, bacteria, and other single-celled or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by swimming towards the highest concentration of food molecules, or to flee from poisons (for example, phenol).

Chemical fertilizers are manufactured chemicals designed to give a boost to plant growth and supply nutrients that are lacking. Usually the most important of these are nitrogen. Nitrogen (N) is important for leaf growth. Phosphorous (P) is needed for root health. Potash (K) is used in flower development. These are the primary chemicals in "complete" fertilizers. Often, small amounts of other chemicals such as sulfur, iron, magnesium, also are included.
