A unique group of organisms including yeast, mould, mildew and mushrooms. Some fungi, such as yeast, are microscopic and some, such as the mushroom, can be seen by the human eye. Fungi reproduce by spores. Some fungi, such as some mushrooms, are edible, most however, are poisonous. Fungi do not have roots and leaves, so do not carry out the process of photosynthesis. There are approximately 70,000 known species of fungi. An important function of fungi is the decomposing of organic matter.
