BIOL 1202 : Biol 1202 Exam Three
Document Summary
Kindome fungi diversity: over 100,000 fungal species identifies and more are added each year, five divisions in the kingdom of fungi. These divisions are based on the dna sequence data, on the presence of septa in the fungi, and on the sexual life cycle: chytids (1,000 species, zygomycetes (1,000 species, glomeromycete (160 species, ascomycetes (65,000 species, basidiomycetes (30,000 species) Ascomycota: they are in roots of oak trees- truffles is in a symbiotic relationship with the tree, ascomycota produces an asccocarp, with millions of ascil (i think it is ascus) each with. Can be found in more than one division: fungi produce antibiotics naturally to kill their competition, ascomycota. How do fungi interact with other species: need to understand fungal lifestyles, use absorption to obtain their food, 3 variations depending on food type. Fungal lifestyles: saprobes: decomposers of dead material (most fungi, parasites: fungi that grow on living organisms (dutch elm disease, corn smut, athletes foot, jock itch, yeast infection).
