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 1.Feeding 2.Structure 3.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. - 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 1.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 3.Yeast - unicellular - undergo anaerobic respiration - used in baking (release CO 2 makes bread rise)
