Presentation Transcript

  1. Fungi Mr. Skirbst Life Science Topic 12

  2. Fungi

  3. Kingdom Fungi Fungus – a plantlike organism lacking chlorophyll

  4. Kingdom Fungi Fungus – a plantlike organism lacking chlorophyll - They are heterotrophic

  5. 3 Characteristics • Feeding • Structure • Reproduction

  6. Feeding - All are heterotrophs

  7. Feeding - All are heterotrophs - They grow on food & absorb it

  8. Feeding - All are heterotrophs - They grow on food & absorb it - Some capture prey

  9. Feeding - All are heterotrophs - They grow on food & absorb it - Some capture prey - Most are decomposers (break down organic material)

  10. Feeding - Some live symbiotically

  11. Feeding - Some live symbiotically (symbiosis – a close relationship)

  12. Feeding - Some live symbiotically (symbiosis – a close relationship) 2 kinds: 1- parasitism – one benefits

  13. Feeding - Some live symbiotically (symbiosis – a close relationship) 2 kinds: 1- parasitism – one benefits 2- mutualism – both benefit

  14. Structure

  15. Structure - Some are unicellular (one cell)

  16. Structure - Some are unicellular (one cell) - Some are multicellular (many)

  17. Structure - Some are unicellular (one cell) - Some are multicellular (many) - Multicellular fungi are made of hyphae (threadlike tubes)

  18. Structure - Some are unicellular (one cell) - Some are multicellular (many) - Multicellular fungi are made of hyphae (threadlike tubes) (cells have many nuclei and can grow very quickly - 40m/hr)

  19. Reproduction - By budding (unicellular fungus, like yeast)

  20. Reproduction - By spores (multicellular fungus, like mushrooms)

  21. 3 Forms of Fungi 1. Mold

  22. 3 Forms of Fungi • Mold “fuzzy” fungi often grows on old food

  23. 3 Forms of Fungi 2. Mushrooms

  24. 3 Forms of Fungi 2. Mushrooms - multicellular - grows a reproductive structure

  25. Mushroom structures

  26. 3 Forms of Fungi 3. Yeast

  27. 3 Forms of Fungi • Yeast - unicellular - undergo anaerobic respiration - used in baking (release CO2 makes bread rise)
