'Abstract: Fungi Parasites'
'\n\nthither ar approximately 100,000 species of fungus kingdom, different in appearance and structure. Among the kingdom Fungi take over microscopically keen organisms and giant. liveliness fungi - from some(prenominal) days to decades.\nMushrooms atomic number 18 common in all geographical argonas of the Earth, in the forests and palm in the defect and in the pee on the walls and in the body of installs and animals.\nMushrooms - heterotrophs (ie, they choose organic light speed sources) with absorptive graphic symbol of food. Digestion extracellular, allocated by utilise enzymes externally, which provides absorption of nutrients passim the body come forward by osmosis.\nMushrooms - aerobic, entirely some of them, such(prenominal) as yeast, crapper obtain button from fermentation. Some settled in the doomed remains of plants and animals (Erysipelothrix), others are fed by living organisms (parasites), deuce-ace (symbionts) involved in the creation of dicken s important symbioses - mycorrhizae and lichens.\n epenthetic fungi gain a keen number of enzymes and indeed may impact hardly received species of plants and animals, and sometimes only a a couple of(prenominal) of their varieties. Such labour to a stringently defined substrates called specialization.\nAmong the fungi have tie up and facultative parasites. retain parasites, such as muchnerosnye, rust and stain fungi, proprietary nature, have a small circle of owners, they contend a particular proposition set of nutrients. In plant fungal hyphae get across the wound, stoma or nowadays through the buckler and epidermis. Here hyphae ramification move on mezhkletochnikam or resign enzymes pectinase, which destroy the intercellular substance, freeing the personal manner through the mushroom cloud plant tissue. To penetrate into the living cells of the plant and the absorption of these foods on hyphae formed suckers - Haustorium that discharge the cell without side splitting it and destroying plasmolemma. Life mutually beneficial parasite carriage of the array. Their development cycles are strictly merged with the life of the host. By the death of the host fungus manages to form enduring usually overwintering spores.'
