l First fungi were probably flagellated. –First fossils – 480 million years ago (Ordovician Period) –Molecular Clock suggests 1 billion years ago (Precambrian).
General Characteristics l Primarily terrestrial l Filamentous –hyphae u coenocytic u septate –mycelium –haustoria
General Characteristics (animal-like) l Heterotrophic –absorption (saprobes) –parasitic –mutualistic l Cell Wall: Chitin l Store sugar as glycogen
Fungal Reproduction l Asexual –haploid spores (conidia/sporangia) l Sexual –plasmogamy (dikaryon) –karyogamy (diploid) –Syngamy (diploid)
Division: Chytrids l Have flagella l Coenocytic hyphae or unicellular l Cell wall: chitin l Saprobes or parasites l May be most primitive fungi
Division: Zygomycota l Coenocytic Fungi l Mostly terrestrial (live on decaying material l Example: Rhizopus (Black bread mold) l Uses: birth control pills, meat tenderizers, margarine coloring
Division: Glomeromycetes l Arbuscular mycorrhizae –Coenocytic Fungi –Mutualistic - associated with plant roots –increases surface area for the absorption of water and nutrients
Diviison: Ascomycetes l Septate fungi (sac fungi) l Saprobes, mutualistic l Examples: Dutch Elm Disease, yeasts, truffles, some molds l Uses: pathogens, food, cooking
Division: Ascomycetes (Deuteromycota) l Imperfect fungi (no sexual cycle) l Examples: Penicillium, Aspergillus, Predatory fungi
l Septate Fungi (Club fungi) l Saprobes, parasites, mutualistic l Examples: mushrooms, toadstools, puffballs, shelf fungi, rusts, smuts l Uses: Food
Division: Basidiomycota l Fairy Rings
Lichen l Mutualistic - association with a green algae or cyanobacteria and an ascomycota or basidiomycota l Pioneer organisms
Microsporidia l Are they Fungi? –Parasitic u Loss of organelles u Tiny organelles derived from mitochondria –Cause disease in people with immune deficiency –Used as pest control
Ecological Impacts l Decomposers l Pathogens l Food Production
Fungi. General Characteristics l Primarily terrestrial l Filamentous –hyphae u coenocytic u septate –mycelium –haustoria.
Fungi. General Characteristics Primarily terrestrial Filamentous –__________ Coenocytic (aseptate) septate –mycelium –Haustoria – specialized parasitic.
Chapter 31 Fungi. Characteristics eukaryotic mostly multicellular, yeasts unicellular no locomotion sexual & asexual reproduction in most heterotrophic.
Fungi Introduction to Fungi Diversity of Fungi Ecological Impacts of Fungi Phylogenetic Relationships of Fungi.
Fungi Classification 1.General Characteristics and structures – These organisms are all multicellular eukaryotes that are heterotrophs and acquire their.
Lecture #13 Date ______ Chapter 31 ~ Fungi. Fungi Heterotrophic by absorption (exoenzymes) Decomposers (saprobes), parasites, mutualistic symbionts (lichens)
True Fungi break down dead organic material provide numerous drugs foods like mushrooms Plant and animal diseases.
Fungi Premier Decomposers Fungi Characteristics Heterotrophic Secrete digestive enzymes on organic material and then absorb it Extracellular digestion.
Plantae Fungi Animalia Protista Monera Kingdom Fungi About 100,000 species Uses: medicine food Ecological value: major decomposers symbiotic relationships.
Fungus Chapter 31 Not as innocent as they look!
FUNGI. What are Fungi? Eukaryotic heterotrophs Cell walls made of chitin Chitin: found in external skeletons of insects Mostly multicellular.
Chapter 31 Reading Quiz 1.What are the filaments called that make up mycelium? 2.What are fungi cell walls made of? 3.What characteristic does “dikaryotic”
Kingdom Fungi I. General Characteristics 1. Found almost everywhere 2. Used to be classified as plants because they were anchored and have cell walls,
Chapter 21 : Kingdom Fungi Page: 527. What types of Fungi do you know? Bread Molds Mushrooms Molds on oranges Yeasts Mildews Rusts & Smuts.
Chapter 23: Fungi Fungus Diversity Identify what fungi are. Describe habitats of fungi. Outline the structure of fungi. Describe fungi reproduction.
FUNGI. KINGDOM FUNGI Nucleated Single celled Multicellular Sexual Asexual Heterotrophs – Saprotroph – Parasites – Symbiosis.
Contractile vacuole action. Amoeboid movement See it!
Kingdom Fungi (ch. 26) If at first you don’t like a fungus … Just wait a little, It will grow on you. Mycology = study of fungi General Characteristics.
Kingdom Fungi Eukaryotic, cell walls made of chitin, saprophytic or parasitic and essential as decomposers.
Kingdom Fungi Common Characteristics: Eukaryotic No chlorophyll and are heterotrophs Cell walls of cells are made of chitin Most are multicellular. Only.
19.5 Diversity of Fungi KEY CONCEPT Fungi are saprobes (decomposers)
Fun With Fungi 31. Characteristics Heterotrophs that acquire nutrients by ______________. Digestion occurs outside the body, secretion of hydrolytic enzymes.
FUNGI. YOU MUST KNOW… THE CHARACTERISTICS OF FUNGI IMPORTANT ECOLOGICAL ROLES OF FUNGI IN MYCORRHIZAL ASSOCIATIONS, AND AS DECOMPOSERS AND PARASITIC PLANT.
Fungi Chapter 31. Fungi - heterotrophs - eat by absorbing nutrients - by secreting enzymes to outside which digest food around them; fungi absorbs food.
Chapter 31 Notes Fungi. Concept 31.1 All fungi are eukaryotic; most are multicellular mycete = fungi Fungi differ from plants in nutritional mode, structural.
Fungi. Characteristics Multicellular (few exceptions like yeast) Eukaryotic Heterotrophic, break down food then absorb, saprotrophic Some are parasitic,
Eukaryotic cells Most are multi-celled Some are uni-cellular Heterotrophs Live in moist, warm areas Have Cell Walls FUNGI.
Fungi. Characteristics eukaryotic multicellular (except yeasts) heterotrophic by absorption (saprophytes – feed on dead organic matter) reproduce sexually.
FUNGI. Fungi General Characteristics eukaryote absorptive heterotroph - saprobe or parasite cell walls made of chitin multicellular (except for yeast)
Chapter 31 – Introduction to Fungi. Fungi characteristics Heterotrophic External digestion Hyphae –Threadlike filaments –Chains of cells can be separated.
©2000 Timothy G. Standish Luke 13:20, 21 20And again he said, Whereunto shall I liken the kingdom of God? 21It is like leaven, which a woman took and hid.
AP Biology Domain Bacteria Domain Archaea Domain Eukarya Common ancestor Kingdom: Fungi Domain Eukarya.
Fungi Chapter 31. Slide 2 of 15 Fungal Commonalities Heterotrophic & Eukaryotic Multicellular Important in the ecosystem as decomposers Cell walls.
Characteristics of Fungi Kingdom Fungi Characteristics Heterotrophic – obtain energy by decomposing organic material Structures are made of the same type.
Fungi Section What is a Fungus? They are heterotrophic eukaryotes with a cell wall They obtain food by extracellular digestion and absorption Enzymes.
Chapter 31 Why did the mushroom go to the party??? Because he’s a fun-gi!
Matt Ponzini, Shane D’Cruz, and Nikhil Popat. Diversity of Fungi 100,000+ species of Fungi are known (Estimated to be 1.5 Million worldwide) Fungi.
Fungi Level 1 Biological Diversity Jim Provan Campbell: Chapter 31.
Fungi (Chapter 31)
Domain Bacteria Domain Archaea Domain Eukarya Common ancestor Kingdom: Fungi Domain Eukarya.
Fungi Chapter Defining Fungi Mycologists believe there may be as many as 1.5 million fungal species Fungi are classified into six main groups -Chytrids.
Fungi. Shared Characteristics Distinctive fungal features – Fungi are heterotrophs. – Fungi have several cell types. – Some fungi have a dikaryon stage.
FUNGI. Plants vs. Fungi Plants have chlorophyll and photosynthesize, fungi do not Plants have roots, leaves, and stems, fungi do not Plant cell walls.
Fungi Unit 8- Chapter 31. What is a Fungi? Usually multicellular Usually multicellular Above ground structures (mushrooms) Above ground structures (mushrooms)
How do Fungi acquire nutients? They are Heterotrophs that get nutrition from absorption -- secretes hydrolytic enzymes into food then absorbs -- therefore.
Kingdom Fungi. Eukaryotic Heterotrophs (decomposers) Cell walls made of chitin –Complex carbohydrate also found in the external skeletons of insects.
Kingdom Fungi is comprised of organisms such as mushrooms, molds, and yeasts, which are eukaryotic heterotrophs that digest food outside of their bodies.
