Document Summary

Lecture objectives: there were no learning objectives given. Fungi are eukaryotic microorganisms including yeasts, moulds and mushrooms. They are classified in a kingdom of their own, one major difference being that fungal cell walls contain the carbohydrate chitin, a long chain polymer of. N-acetylglucosamine (a derivative of glucose) and -1-3 glucan. Plant cell walls and those of some protoctists contain the carbohydrate cellulose. Nutritionally, fungi are heterotrophic organisms that rely solely on carbon fixed by other organisms for metabolism and feed by absorption. The fungal life cycle can be simple or complex and fungi can reproduce by sexual or asexual means. There are two cellular forms of growth in fungi: blastospores: as seen in yeast cells. A blastospore is an asexual fungal spore produced by budding. Yeasts are unicellular fungi and do not grow as hyphae: hyphae: as seen in moulds. A hypha is a long branching filamentous structure and the main method of vegetative growth; collectively called a mycelium.
