1 FUNGI

2 Plants vs. Fungi Plants have chlorophyll and photosynthesize, fungi do not Plants have roots, leaves, and stems, fungi do not Plant cell walls are polysaccharide cellulose, fungal cell walls are not

3 General Characteristics eukaryote
Fungi General Characteristics eukaryote absorptive heterotroph - saprobe or parasite cell walls made of chitin multicellular (except for yeast) reproduce with spores

4 Basic Structure Hyphae- thin filaments making up a fungus (some called rhizoids help to anchor the fungus) Mycelium- mass of tangled filaments (hyphae); most of these are in soil or embedded in host’s tissue Fruiting body­- reproductive structure; what you see Spores- thick-walled; located at tips of some hyphae; for reproduction

5 Structure hyphae Fungi

6 Structure mycelium Fungi

7 extracellular digestion enzymes are secreted into food source
food source is digested by enzymes nutrients are absorbed by fungus Fungi

8 fungal spores dispersed Spores that reach food source – germinate
Life Cycle fungal spores dispersed Spores that reach food source – germinate hyphae penetrate into food Nutrients are absorbed mycelium grows from the food fruiting body is made releases spores Read pages 591 and 592 Fungi

9 Fungi are diverse and are classified based on their
reproductive structures (how they produce spores)

10 common name - common molds ex – bread mold reproduction
Phylum Zygomycota common name - common molds ex – bread mold reproduction asexual – spores from sporangium sexual - zygospore forms when hyphae of different sexes fuse together; thick walled zygospore is formed uses – parasite, saprobe Fungi

11 common name – club fungi
Phylum Basidiomycota common name – club fungi ex – mushrooms, shelf fungi, smuts, rusts, puffballs reproduction basidiospores basidia – club shaped structure where spores form on gills uses – many are edible; plant disease; poisonous (toadstools) Fungi

12 smuts rusts stinkhorn shelf fungi

13 Fungi puff balls mushrooms

14 ex – yeast, powdery mildews, morels reproduction
Phylum Ascomycota common name – sac fungi ex – yeast, powdery mildews, morels reproduction asexual – conidiophores (clusters of spores) sexual – ascospores produces in ascus (sac like structure) uses – brewing, baking, research, plant diseases, some are edible Fungi

15 Morels Yeast Powdery mildews
Fungi Morels Yeast Powdery mildews

16 common name – imperfect fungi
Phylum Deuteromycota common name – imperfect fungi ex – penicillium, ring worm, athlethe’s foot, jock itch reproduction only asexual uses – penecillin / antibiotics, soy sauce, bleu cheese, citric acid Fungi

17 Fungi ring worm

18 Athlete’s foot (ring worm) Nail fungus
Fungi Athlete’s foot (ring worm) Nail fungus

19 mutualistic relationship
Phylum mycophycota common name – lichen mutualistic relationship fungus & green algae, neither could live alone algae provides food, fungus provides protection and minerals reproduction (skip) uses – food for animals, pioneer species, starts soil in some places Fungi

20 Fungi lichen

21 Good and Bad Things About Fungi
The Good Decomposers (nutrient cycling) Some medicines Penicillin Some food Blue cheese Mushrooms Habitat The Bad Some poisonous Some parasitic Some disease-causing Athlete’s foot Ringworm Yeast infections/ jock itch
