Cecidology is the scientific study of galls, which are abnormal growths that occur on plants, often caused by insects, fungi, or bacteria. These growths can take various forms, such as lumps or swellings, and serve as a habitat or food source for the organisms that induce them. Galls can be found on leaves, stems, roots, and even flowers, showcasing the complex interactions between plants and other living organisms. Researchers in cecidology examine the mechanisms behind gall formation and the ecological roles they play in ecosystems. This field contributes to our understanding of plant health, pest management, and biodiversity, highlighting the intricate relationships within nature, including those involving insects and plants.
