Fungi are simple plants that grow on other living things. They do not have roots, stems and leaves like other plants. Fungi are much closer to animals than plants because of their biology. They are found growing in moist places as they need water for the digestion of food and growth. They lack chlorophyll and are dependent on other living things because they cannot make their own food. There are different kinds of fungi, such as yeast, mushrooms and toadstools.
