Tropism Notes:

A tropism is a phenomenon that indicates growth or turning movement of a biological organism, which is usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus. Viruses and other pathogens also affect what is called "host tropism", "tissue tropism", or "cell tropism"; in which case tropism refers to the way in which different viruses/pathogens have evolved to preferentially target specific host species, specific tissue, or specific cell types within those species. Tropisms are usually named for the stimulus involved (for example, a phototropism is a directional movement in response to sunlight).
