FUNGI


Most fungi are multi cellular. Yeast is an exception and it is a unicellular fungus. Multi cellular fungi are made up of hyphae. Hyphae are fine thread like structures.
                          No chlorophyll is present in fungi. Fungi are saprophytic, parasitic or symbiotic. Saprophytic means living on dead organic matter.                                 
                     Parasitic means grows feeds and shattered on or in a different organism while contributing nothing, to the survival of its host. Symbiotic means helping each other for nutrition.(mutually advantageous) eg. Lichens are a symbiotic partnership between algae and fungi.
                                     Yeast feed by changing sugars into alcohol, a process known as fermentation
