1. 7.3 Kingdom Fungi

2. What are Fungi?
Most fungi share three important characteristics: They are eukaryotes, use spores to reproduce, and are heterotrophs that feed in a similar way.

3. Cell Structure
The structures that make up the bodies of multicellular fungi are called hyphae.

5. How Do Fungi Obtain Food?
The chemicals that ooze from the hyphae of a fungus into a food source break down the food.

6.                                                                                                     
Athlete's foot is caused by a fungus that feeds on chemicals in a person's skin.

7. Yeasts differ from most other fungi because they are unicellular. 

8. Reproduction in Fungi
Fungi produce spores in structures called fruiting bodies.

9. Asexual Reproduction
When there is adequate moisture and food, most fungi reproduce asexually by growing fruiting bodies that release thousands of spores.

10. See where the bud came off?
Asexual Reproduction
Unicellular yeast cells undergo a form of asexual reproduction called budding.

11. Sexual Reproduction
If growing conditions are unfavorable, the hyphae may grow together to exchange genetic material.
Why is this advantageous?

12. Classification of Fungi
Fungi are classified into groups depending on the shape of their spore-producing structures.
There are four groups:

13. Threadlike Fungi
Rhizopus sporangia X 40

14. Cyathus olla bird's nest fungi
Sac Fungi
Cyathus olla bird's nest fungi

15. Hypholoma rasciculare
Club Fungi
Hygrocybe collucera
Hypholoma rasciculare
Puffballs - Lycoperdon perlatum

16. Imperfect Fungi
penicillin
Penicillium Conidia X 400

17. Fungi and the Living World
Fungi that decompose dead organisms return important nutrients to the soil.

18. Bakers add yeast to bread dough to make it rise
Bakers add yeast to bread dough to make it rise. Yeast cells use the sugar in the dough for food and produce carbon dioxide gas as they feed.

19. The antibiotic penicillin resulted from the work of Alexander Fleming, who noticed that bacteria did not grow near a spot of mold in a petri dish.

20. A + F = L
A Lichen consists of a Fungus and an Alga that live together in a mutualistic relationship.
