1. Kingdom Fungi
Ch. 10 pg.364

2. Fungus are adapted for 2 main functions
Absorption of nutrients
Reproduction

3. 300 million years ago:
Fungus took a different evolutionary pathway than plants
They adapted to a heterotrophic way of life and lost the ability to be autotrophs

4. Similarities between plants and Fungi
Both are eukaryotic
Both have cell walls
Most are anchored in the soil or substrate
Reproduction can be sexual or asexual or both
Both are stationary

5. Differences Plants Fungi Have one nucleus per cell
Often have many nuclei per cell
Are autotrophs
Are heterotrophs
Most have roots
Have no roots
Have cellulose in the cell walls
Often have chitin in the cell walls
Some reproduce by seed
None reproduce by seed

6. Fungi are classified by how they reproduce (produce spores).
Ex:
Sac Fungi - yeast, morels, truffles
Club Fungi – mushrooms, shelf fungi
Imperfect fungi – disease causing fungi, penicillium

7. Yeast & Morels (Sac Fungi)

8. Truffels – Sac Fungi

9. Shitake Mushrooms – club fungi

10. Penicillium - Imperfect fungi

11. Terms
Hypha (hyphae) – branching filaments that are usually on or below the surface of the substrate
Mycelium – a mesh of hyphae

12. Importance of Fungi
Decomposers – they are an important part of nature’s recycling
Benefit to humans – yeast is used to make bread, wine & beer
Penicillium – used to produce antibiotics
Aspergillus – used to flavour soft drinks
Food items –mushrooms, morels, truffles

13. Athlete’s Foot

14. Between the toes

15. And it gets worse…

16. Ringworm

17. Ringworm is a pathogenic fungi

18. Ringworm affects our pets too

19. How to treat ringworm infections

20. Yeast infections

21. Fungus Symbiosis
Symbiosis is a relationship between 2 organisms that survive together
LICHENS are an example of this
Lichens are green algae living with a fungus
Green algae provide the food through photosynthesis
Fungi provide protection by surrounding the algae and giving CO2 and H2O
