Protist and Fungi Notes: Chapter 19 & 20

6 Kingdoms Archaebacteria Archaebacteria Eubacteria Eubacteria  Protist  Fungi  Plant  Animal

Protists:  Intro movie Intro movie Intro movie  Junk-Drawer: Most diverse kingdom  Eukaryotes: mostly unicellular but some multicellular  Live in moist environments

Protists:  Move by using flagellum, cilia, pseudopods (“false feet”)  Can cause disease: –Ex: malaria (protist lives inside mosquito)

Protozoans: Animal – like protists  Unicellular heterotrophs  Usually reproduce asexually (one parent makes identical offspring)  Ex: amoeba (move by pseudopodia), paramecium

Algae: Plant- like protists  Autotrophs: Carry out photosynthesis, contain chlorophyll  Many colors depending on pigment  Not plants because no roots, stems, or leaves

Fungus-like protists:  Heterotrophs: decompose organic material  Cause damage to crops (Ireland potato famine)  Ex: slime molds, downy mildews  Slime molds helping build roads! Slime molds helping build roads! Slime molds helping build roads!

Fungi: What is a fungis? What is a fungis?

Fungi:  Eukaryotes: mostly multicellular, some unicellular  Cell wall of chitin  Heterotrophs: decomposers; extracellular digestion

Fungi:  Threadlike filaments called hyphae form a mycelium (fruit or vegetative part of fungus)  Reproduction: –Asexual reproduction by producing spores or by budding; –Sexual reproduction

Fungi:  Examples: blue cheese, penicillin, athlete’s foot, mushrooms, food mold, baker’s yeast  Mycologists: scientists who study fungi
