Question

what is fungi ? how some of them are beneficial and some are harmful for mankind​

Answer 1

Answer:

Human interactions with fungi include both beneficial uses, whether practical or symbolic, and harmful interactions such as when fungi damage crops, timber, or food.

Wine has been made using grapes and natural yeast since ancient times. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt

Yeasts have been used since ancient times to leaven bread and to ferment beer and wine. More recently, mould fungi have been exploited to create a wide range of industrial products, including enzymes and drugs. Medicines based on fungi include antibiotics, immunosuppressants, statins and many anti-cancer drugs. The yeast species Saccharomyces cerevisiae is an important model organism in cell biology. The fruiting bodies of some larger fungi are collected as edible mushrooms, including delicacies like the chanterelle, cep, and truffle, while a few species are cultivated. Mould fungi provide the meaty (umami) flavour of fermented soybean products such as tempeh, miso and soy sauce, and contribute flavour and colour to blue cheeses including Roquefort and Stilton. Moulds also yield vegetarian meat substitutes like Quorn. Some fungi, especially the fly agaric and psilocybin mushrooms are used for the psychoactive drugs that they contain; these in particular are the focus of academic study in the field of ethnomycology. Fungi have appeared, too, from time to time, in literature and art.

Fungi create harm by spoiling food, destroying timber, and by causing diseases of crops, livestock, and humans. Fungi, mainly moulds like Penicillium and Aspergillus, spoil many stored foods. Fungi cause the majority of plant diseases, which in turn cause serious economic losses. Sometimes, as in the Great Irish Famine of 1845–1849, fungal diseases of plants, in this case potato blight caused by Phytophthora, result in large-scale human suffering. Fungi are similarly the main cause of economic losses of timber in buildings. Finally, fungi cause many diseases of humans and livestock; Aspergillosis kills some 600,000 people a year, mainly however those with already weakened immune systems

Answer 2

Answer:

• These organisms may look like plants but they are not plants because they do not make their own food.
• Mold fungi reproduce using spores.
• These are single cells made by the fungus.
• Spores are very light and so travel easily in the air.
• When they land on a source of food they grow into new molds.
• Fungi grow best in damp and warm places.
• As food - food like mushrooms and dried yeast which provide us protein and vitamin
• In agriculture - like making the soil fertile
• Human diseases
