Transcript of Kingdom Fungi
Kingdom Fungi
Characteristics• Eukaryotic • Heterotrophic
– Digest food outside of their bodies• Multicellular, except for yeasts (unicellular)• Present all over the world
– marine and terrestrial environments• Cell walls contain chitin• Main body composed of hyphae• Reproduction involves sexual and asexual
phases
• Most fungi grow as tubular filaments called hyphae. An interwoven mass of hyphae is called a mycelium.
• The walls of hyphae are often strengthened with chitin
• Fungi reproduce by releasing spores from a fruiting body. The spore is released into the air and the wind carries it off to start the next generation.
• Composed of mushrooms, molds and yeast
• Mycorrhizae– symbiotic relationships
with plants, work as partners
– Soil fungi attach themselves onto plant roots
– Fungi helps plants absorb more water and nutrients, while plant provides food for fungi
• Use in everyday life: making bread (yeast), antibiotics (ie. Penicillin), eating (mushrooms)
• Mushrooms are Fungi!
• Club Fungi – look like umbrellas growing from the ground or like shelves
• Sac Fungi – produce spores in special sacs called asci
• Lichens – union between fungus and algae
• Conjugation Fungi – black bread mold
• Imperfect Fungi – left-overs , penicillin
• Penicillin– First antibiotic– Attacks and kills bacteria
• Very good decomposers!
Human Fungus Diseases• Ringworm• Athlete’s foot• Amanita – death cap
