Abstract: One of the main characteristics that distinguish fungi from plants and animals is the fact that they do not eat food, they absorb it. This experiments aims to look at the response of pathogenic fungi when in the presence of allelopathic plants that secrete toxic chemicals. This experiment is attempting to determine if the toxic environment created by allelopathic plant affects the pathogenic fungus or if the pathogenic fungus affects the growth and survival of the allelopathic plant. To carry out this experiment, it is necessary that researchers grow a pathogenic fungus with an allelopathic plant as well as grow the fungus and plant separately in soil. For a period of 2 weeks, researchers should water the plant and fungus experimental plot as well as controls with the same amount of water and measure the growth of all plant and fungi everyday. This researcher believes that the results of this experiment will be that the fungus is superior to the allelopathic plant and the plant will die due to the fungus taking over it and killing it. Introduction: Fungi and Plants are very different. One large differentiating characteristic is the way both organisms eat. Fungi extend their hyphae into the food source, secrete chemicals to help break down the food, and then absorb them. However, plants are autotrophs and make their own food through photosynthesis. Many fungi form mutualistic symbiotic relationships with plants called mycorrhizae, some fungi act as decomposers, while a third group of fungi act as pathogens and attack plants by stealing their source of nutrients usually ending with the death of the plant. Pathogenic fungi take over some plants by growing in their stomates or making holes in their epidermis. Next, the fungi poison and kill the plants so that they can absorb nutrients from them or the fungi steal nutrients from the plant’s living cells. In this experiment, researchers will simulate an interaction between a pathogenic fungus and an allelopathic plant in order to determine the results of the cohabitation of these two organisms. The study of fungi that attack plants is called plant pathology. This is an important field of study because many pathogenic fungi negatively affect crop growth and the agricultural industry. It is important to study plants that could potentially combat the affects of these pathogenic fungi. If plants of this nature are discovered, than the specific mechanism the plant uses (allelopathy) and the specific nature of the mechanism could then be studied to see if it can be re-enacted in some way with other plants to combat pathogenic fungi and therefore used in crops. This research could potentially be comparable to the invention of
