Fungi are like plants in many aspects: they grow rooted to the ground, they do not move. However, fungi do not photosynthesise, and do not have chlorophyll. Therefore, in order to feed, they produce enzymes which seep out of the fungus into a living or dead organism. The enzymes then digest the food, and the fungus soaks it up - this is known as saptotrophic feeding.

Parts of a fungus[edit | edit source]

The main body of a fungus is called a mycelium - this is made of many threads (hyphae). These grow through whatever the fungus is feeding on, or alternatively through the soil. Each hypae is surrounded by a cell wall made of chitin (usually - some have other substances in the cell walls). Sometimes, fungi grow a 'mushroom' above the ground  - this is for reproduction, done by producing thousands of tiny spores.

Yeast[edit | edit source]

Yeast is a strange fungus - it has no hyphae or mycelium, and lives as single cells.
