1 KINGDOM FUNGI CP Biology - Chapter 21 Paul VI Catholic High School

2 FUNGI FUNGI ARE HETEROTROPHS FILAMENTOUS BODIES –HYPHAE & MYCELIA NUCLEAR EXCHANGE

3 FUNGI

4 CELL WALLS OF CHITIN NUCLEAR MITOSIS –NUCLEAR ENVELOPE REMAINS INTACT –MITOSIS OCCURS WITHIN THE SPINDLE (PLAQUES) EXTRACORPOREAL DIGESTION

5 FUNGI FAIRY RING: Reproductive structures of subterranean fungus

6 FUNGI FOUR MAIN GROUPS: ZYGOMYCETES ( Common Molds ) ASCOMYCETES ( Sac Fungi ) BASIDIOMYCETES ( Club Fungi ) DEUTEROMYCETES ( Imperfect Fungi)

7 FUNGI ZYGOMYCETES ( Common Molds ) RHIZOPUS STOLONIFER HYPHAE: STOLONS RHIZOIDS SPORANGIOPHORES

8 FUNGI

9 REPRODUCTION: ASEXUAL Haploid Spores SEXUAL GAMETANGIA PLASMOGAMY KARYOGAMY

10 FUNGI

11 ZYGOMYCETE: Pilobolus

12 FUNGI Rhizopus decomposing strawberries

13 FUNGI ASCOMYCETES : ( Sac Fungi ) –Truffles & Morels –Conidia forms asexual spores –Ascus contains spores from sexual reproduction –Ascocarp: “Fruiting Body”

14 FUNGI ASCOMYCETE: Scarlet Cup Fungus

15 FUNGI Truffles

16 FUNGI MOREL

17 FUNGI

18

19 ERGOT: Active ingredient in LSD

20 FUNGI BASIDIOMYCETES: ( Club Fungi ) –Basidium (lat.) “Pedestal” –Toadstools, Mushrooms, Puffballs –Basidiocarp is “Fruiting Body” –Gills contain the spores –Some varieties poisonous

21 FUNGI Varieties of Basidiomycetes

22 FUNGI

23 Poisonous varieties Basidiomycetes

24 FUNGI AMANITA PHALLOIDES “Death Angel”

25 FUNGI AMANITA PHALLOIDES Small ingestion sufficient for death RNA Polymerase Inhibitor Onset 6-12 Hrs.- Duration 5-7 Days Death from Kidney, Liver Failure No Treatment; No Antagonist

26 FUNGI AMANITA MUSCARINA Muscarinic Effects –Pinpoint Pupils –Excessive sweating, salivating –Low Blood Pressure –Nausea, Vomiting –Lower Heart Rate –Atropine Antagonist

27 FUNGI Amanita muscarina

28 FUNGI DEUTEROMYCETES: (Imperfect Fungi) –“Imperfectly Understood” –Beneficial & Harmful Varieties Yeast (Saccharomyces cerevisiae) Aspergilla Cutaneous Diseases Penicillium notatum

29 FUNGI Cutaneous Lesions of Deuteromycetes

30 FUNGI Penicillium notatum Sir Alexander Fleming

31 FUNGI SYMBIOTIC FUNGAL ORGANISMS LICHENS –Combination of Fungus Usually Ascomycete Occasionally Basidiomycete and either: Photosynthetic bacterium Green Algae

32 FUNGI

33

34 FUNGUS LICHENS (cont’d): –“Pioneer Colonies” –Pigment used for dyes –Litmus Paper –Indicator of Air Quality

35 FUNGI SYMBIOTIC FUNGAL ORGANISMS MYCORRHIZAE: –Mutualistic association plant & fungi –Found in over 90% vascular plants –Enhance nutrient availability to plant –Receive glucose from plant

36 FUNGI SYMBIOTIC FUNGAL ORGANISMS MYCORRHIZAE: –ENDOMYCORRHIZAE: Usually Zygomycete Fungus enters into plant cell –ECTOMYCORRHIZAE: Usually Basidiomycete Fungus does NOT enter plant cell

37 FUNGI
