  1. Fungi

  2. General Characteristics • Heterotrophic- can get nutrition 2 ways 1. Produce an enzyme that digests organic material outside of the fungus. Then fungus absorbs the liquidated nutrients 2. Produce Haustoria- hyphae penetrate the host cell and suck up the nutrients directly form the host- doesn’t kill the host cell, just feed off it. (Parasitic) • Decomposers-saprobe • Live in moist ,cool environments

  3. Basic Structure • Hyphae • Group of Hyphae- called a mycellium

  4. Reproduction-2 ways • Asexually- a. through FRAGMENTATION where a piece breaks off and grows b. BUDDING- yeast pinch off a piece and become 2 cells

  5. Sexually- produce spores (Bread mold)

  6. 4 Types of Fungi • Imperfect: no observable sexual reproduction Deuteromycota: penicillin

  7. Diseases Plant • Mildew • Wheat rust Animal • Athletes foot • Candida albicans • Ringworm

  8. Lichen • Special relationship between a fungi and algae • Mutualistic relationship • Fungi provides safe place to live • Algae provides food through photosynthesis

  9. Mycorrhizae • Mutualistic relationship with plant • Fungi grow on roots of plants • Fungi help increase the surface area at the roots so plants can absorb more water
