General Characteristics: Heterotrophic (must feed) organisms which lack chlorophyll Heterotrophic – obtain food by “decomposing” Chlorophyll – used by plants for photosynthesis 2 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? 3 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? 4 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? Are Multicellular, Eukaryotic, and Filamentous Eukaryotic – cells have internal organelles Multicellular – made of many cells 5 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? Are Non-Motile Have no means of movement Have Cell Walls 6 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? 7 M.Bregar (Dante C.S.S.) What is a fungus? : What is a fungus? 8 M.Bregar (Dante C.S.S.) Classification : Classification 9 M.Bregar (Dante C.S.S.) Classification : Classification Once classified as plants, but now exist within their own kingdom 10 M.Bregar (Dante C.S.S.) Similarities Between Fungi & Plants : Similarities Between Fungi & Plants Similarities between fungi and plants: Eukaryotic cells Have cell walls & numerous organelles Anchored in soil / substrate Reproduction can be asexual, sexual, or both Are stationary Note – Fungi are more closely related to animals than plants 11 M.Bregar (Dante C.S.S.) Differences Between Fungi & Plants : Differences Between Fungi & Plants Differences include: Fungi: Many nuclei Heterotrophs No storage molecule No roots No seeds Cell Walls have chitin Plants: 1 nucleus Autotrophs Starch is storage molecule Have roots Reproduce by seeds Cell Walls have cellulose 12 M.Bregar (Dante C.S.S.) Fungi Structure : Fungi Structure 13 M.Bregar (Dante C.S.S.) Fungi Structure : Fungi Structure Fungi consists of many eukaryotic cells together, to form strands of tissue called hyphae 14 M.Bregar (Dante C.S.S.) Hypha : Hypha 15 M.Bregar (Dante C.S.S.) Hypha : Hypha 16 M.Bregar (Dante C.S.S.) Hypha : Hypha 17 M.Bregar (Dante C.S.S.) Hypha : Hypha Hypha (pl. – hyphae) Filaments making body of a fungus Fungi cells have a cell wall with a tubular shape Septum – walls which separate individual cells 18 M.Bregar (Dante C.S.S.) Hypha : Hypha 19 M.Bregar (Dante C.S.S.) Hypha : Hypha 20 M.Bregar (Dante C.S.S.) Hypha : Hypha 21 M.Bregar (Dante C.S.S.) Hypha : Hypha Mycelium Many filaments (hypha) make the mycelium Location of nutrient absorption 22 M.Bregar (Dante C.S.S.) Functions of Fungi : Functions of Fungi 23 M.Bregar (Dante C.S.S.) Functions of Fungi : Functions of Fungi Fungi are adapted for two main functions: Nutrient Absorption Reproduction 24 M.Bregar (Dante C.S.S.) Important Definitions : Important Definitions Digestion (def) Process of breaking down food into simpler molecules Absorption (def) Broken nutrients are absorbed by an organism 25 M.Bregar (Dante C.S.S.) Nutrient Absorption : Nutrient Absorption Digestion is External Fungi are decomposers which “live on their food” Secrete digestive enzymes into environment Therefore, nutrients are chemically broken down outside of the fungi 26 M.Bregar (Dante C.S.S.) Nutrient Absorption : Nutrient Absorption 27 M.Bregar (Dante C.S.S.) Nutrient Absorption : Nutrient Absorption Nutrient Absorption Nutrients are absorbed in the mycelium Located on substrate or below its surface 28 M.Bregar (Dante C.S.S.) Nutrient Absorption : Nutrient Absorption 29 M.Bregar (Dante C.S.S.) Reproduction : Reproduction Reproduction in fungi: Can be asexual or sexual Asexual reproduction is more common Fungi reproduce via spores Each group of fungi has a unique set of spores. 30 M.Bregar (Dante C.S.S.) Asexual Reproduction : Asexual Reproduction Asexual reproduction takes place when environmental conditions are favorable Budding Simplest form 1 cell grows or “pinches” out of another 31 M.Bregar (Dante C.S.S.) Asexual Reproduction – Budding : Asexual Reproduction – Budding 32 M.Bregar (Dante C.S.S.) Asexual Reproduction : Asexual Reproduction Fragmentation Piece of mycelium breaks up Grows into whole new organism 33 M.Bregar (Dante C.S.S.) Asexual Reproduction : Asexual Reproduction Sporulation (spores) Most common form of reproduction Spores released and grow into new organism 34 M.Bregar (Dante C.S.S.) Asexual Reproduction - Sporulation : Asexual Reproduction - Sporulation 35 M.Bregar (Dante C.S.S.) Sexual Reproduction : Sexual Reproduction Occurs when environmental conditions are unfavorable Allows fungi to adapt to new environment conditions Spores are produced in both sexual and asexual reproduction Mating Types No male or female plus (+) and minus (-) 36 M.Bregar (Dante C.S.S.) Sexual Reproduction : Sexual Reproduction Fertilization occurs when (+) hyphae fuse with (-) hyphae 37 M.Bregar (Dante C.S.S.) Sexual Reproduction : Sexual Reproduction 38 M.Bregar (Dante C.S.S.) Sexual Reproduction – Spores : Sexual Reproduction – Spores 39 M.Bregar (Dante C.S.S.) Fungi & The Environment : Fungi & The Environment 40 M.Bregar (Dante C.S.S.) Importance of Fungi : Importance of Fungi Decomposers & Recyclers of nutrients in environment Symbiotic relationships (fungal hyphae help plant’s root absorb nutrients i.e.phosphorous) Lichens - air quality monitors (composed of fungi and algae) 41 M.Bregar (Dante C.S.S.) Fungi & Humans : Fungi & Humans Fungal spores cause allergies Molds, mildew, rusts, & smuts damage crops Yeasts are used to make beer & bread Antibiotic penicillin 42 M.Bregar (Dante C.S.S.)
