United fungi including heterotrophic cellular organisms possess thickened cell walls by chitin and cells with functional specialization. Also called fungi. The specialty of biology, medicine and botany dealing with fungi is called mycology.
Fungi are eukaryotic (nucleated cells) that carry out external digestion of food by secreting enzymes, and then take up the dissolved molecules resulting from the digestion, ie, feeding osmotróficamente (like plants) absorbing dissolved substances, but unlike those, taking nutrients are organic. Fungi are the primary decomposers of dead matter of plants and animals in many ecosystems, and are commonly seen on stale bread.
fungi have vegetative structures much more organized and independent of aquatic life. Their vegetative body consists of more branched vegetative structures are hyphae, the mycelium can be arranged in-house or external guests.
Fungi are very important in recycling organic matter (eg saprophytic fungi in the litter). Domina chitin in cell walls, and as usual are able to eliminate powerful enzymes to degrade all organic matter, biodegradable presented to then absorb the result.
mycelia are well developed, the mushroom is a small portion of the fungus itself. The mycelium can not withstand dehydration and must be protected on the inside of something, so that only the reproductive part comes out. Most fungi are multicellular and plurinucleados, and even pseudoparenquimáticos. Lateral hyphae, but not related to weld. The kingdom fungi lack flagella.
