There is so much to say about Fungi! But I will give you a brief overview of some important characteristics. The Kingdom Fungi is separate from plants, animals, protists, and bacteria. It it composed of eukaryotic organisms such as yeasts, mold, and mushrooms. Their cell walls are composed of a material called chitin, which is different from the material that plant cell walls are made of. Many are small in size and live in soil matter where they play an essential role in the decomposition of organic matter and nutrient cycling. Another aspect of fungus is that they can be symbionts, meaning they interact and live with different biological species to help or harm them.

The study of fungi is called Mycology. One kind of fungus is a yeast, which many scientists use as a model organism in research. If you didn't know, the reason of bubbles in breads is due to yeast. Although some types of fungus may do good for the environment and for people, many cause diseases in humans, such as yeast infection and athlete's foot. They can also cause plant diseases which may lead to death of plants.
