Fungi All are: Eukaryotes Use spores to reproduce Heterotrophs that feed in a similar way.
Cell Structure • Yeast are unicellular • Other fungi have cells arranged in structures called hyphae (hy-fee) • Hyphae are branching, threadlike tubes that make up the bodies of multicellular fungi. Substances move quickly and freely through hyphae. • The appearance of fungus depends on how the hyphae are arranged.
Obtaining Food • Fungus grows hyphae into the food source. • Digestive chemicals ooze from tips of hyphae into food. • These chemicals breakdown the food so it can be absorbed by hyphae.
Reproduction • Fungi reproduce through spores (a tiny cell that is able to grow into a new organism) • Spores are produced in structures called fruiting bodies. • Unicellular yeast undergo budding (no spores), just a small cell growing off of a parent cell.
More on reproduction… • These 2 forms of reproduction are called asexual reproduction where the reproductive process involves only 1 parent and produces offspring identical to the parent. Fungi use this method when conditions are favorable. • Fungi use sexual reproduction (reproductive process involving 2 parents) when conditions are unfavorable.
Important Roles of Fungi • Environmental recyclers (decomposers) • Food (mushrooms, cheese, bread, beer & wine) • Disease (athlete’s foot, corn smut) • Disease fighting (penicillin) • Lichens (a fungus & algae or bacteria living together in a symbiotic relationship), helps create soil There are 4 types of Fungi, see the handout!
Last note: • A mushroom went into a bar and saw some algae at a table. He went up to one and said "You're lookin' all gal." She looked him over and said "You look like a fun guy." And they took a liken to each other. • The End!
