Document Summary
Fungi are closer related to animals than plants. Human influences on fungi: on food in fridge. Hugely important ecologically in the decomposition of organic material: opportunistic, seek nutrients wherever they find them, found everywhere. Symbitical relationshiips: mycorrhizae, fairy ring: growing from single source in middle, hyphae growing out in, signal: sexually reproduce and produce spore, spread spores. Food soilage: mass scale, harvested plants, organic matter can be ruined quickly if fungal spres get in ad around produce, unpleasant economic waste, many fungal species produce toxic byproducts. Used to produce antimicrobial compounds antibiotics. By far most abundant if ascomytes and bascidiomyceytes (mushroom: more evolutionary advances. Important for plant pathogens most major ones are one of these two. Classification: how the hyphae are organized, aseptic or septic: do hyphae have wall or not. Mode of reproduction varies: sexual and asexual, chytrids: unmotile spores.
