Kingdom Fungi :
These are eukaryotic heterotrophs showing extracellular digestion. They are found in warm and humid places. They have simple body which may be unicellular or made up of long thread like structures called hyphae. Large fungi such as mushrooms have a compact mass of cells. Unicellular organisms have a protoplast with many nuclei. e.g. Rhizopus, Saccharomyces (Yeast-unicellular fungus).
Filamentous fungi consist of a body called mycellium in which hyphae are present. The hyphae may be with septa or without septa. They may be uni or multinucleate. The non-septate multinucleate hyphae are called coenocytic hyphae. The cell wall in fungi is composed of chitin, a polysaccharide or fungal cellulose. The fungi exhibit hetrotrophic mode of nutrition. Mostly they are saprophytic, some are parasitic or predators.
They reproduce sexually as well as asexually. Asexual reproduction takes place by fragmentation, fission and budding. Some fungi are symbiotic; either live with algae as lichens or as mycorrhiza in association with roots of higher plants. They are useful as well as harmful. Mushrooms are consumed as food, yeast is used in bakery and breweries. Penicillium, a fungus, is well known for antibiotic production. Harmful fungi cause diseases in plants and animals. e.g. Puccinia.
