First classified as plants, fungi are now considered different enough from plants to be placed in a separate kingdom, and in fact are more like animals than plants.
http://www.fungi.euFungi is used to be classified as plants, why are they now classified in a separate kingdom?
Fungi were classified as plants because they had cell walls and formed spores similar to those formed by plants. Further investigation showed that fungi secrete exoenzmyes and absorb nutrients from pre-formed organic molecules, thus are heterotrophic rather than autotrophic like plants. The cell walls are of chitin rather than cellulose found in the cell walls of plants.
