the phylum that each character belongs to Porifera Tuesday, February 19, 13 Echinodermata Bell Work identify the phylum that each character belongs to Porifera Tuesday, February 19, 13 Echinodermata Mollusca Bell Work identify the phylum that each character belongs to Porifera Chordata Tuesday, February 19, 13 Echinodermata Mollusca Bell Work identify the phylum that each character belongs to Tuesday, February 19, 13 Porifera Echinodermata Chordata Mollusca Mollusca Bell Work identify the phylum that each character belongs to Tuesday, February 19, 13 Porifera Echinodermata Mollusca Chordata Mollusca Arthropoda Characteristics of Fungi Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells • heterotrophs (decomposers) Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells • heterotrophs (decomposers) • cell wall made of chitin Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells • heterotrophs (decomposers) • cell wall made of chitin • can be either: Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells • heterotrophs (decomposers) • cell wall made of chitin • can be either: • unicellular (yeast) Tuesday, February 19, 13 Characteristics of Fungi • eukaryotic cells • heterotrophs (decomposers) • cell wall made of chitin • can be either: • unicellular (yeast) • multicellular (mushrooms, mold) Tuesday, February 19, 13 Fungi Nutrition Tuesday, February 19, 13 Fungi Nutrition • fungi get nutrients by sending out threadlike structures called hyphae Tuesday, February 19, 13 Fungi Nutrition • fungi get nutrients by sending out threadlike structures called hyphae •hyphae release enzymes that break down food Tuesday, February 19, 13 Fungi Nutrition • fungi get nutrients by sending out threadlike structures called hyphae •hyphae release enzymes that break down food • extracellular digestion Tuesday, February 19, 13 Fungi Nutrition • fungi get nutrients by sending out threadlike structures called hyphae •hyphae release enzymes that break down food • extracellular digestion • food particles then diffuse into the hyphae Tuesday, February 19, 13 Fungi Reproduction Tuesday, February 19, 13 Fungi Reproduction • Yeast reproduce asexually Tuesday, February 19, 13 Fungi Reproduction • Yeast reproduce asexually • Budding: Tuesday, February 19, 13 Fungi Reproduction • Yeast reproduce asexually • Budding:: a new yeast grows from a parent and eventually breaks off Tuesday, February 19, 13 Fungi Reproduction • Yeast reproduce asexually • Budding:: a new yeast grows from a parent and eventually breaks off • Fission: Tuesday, February 19, 13 Fungi Reproduction • Yeast reproduce asexually • Budding:: a new yeast grows from a parent and eventually breaks off • Fission::yeast splits in half to form two yeast cells (mitosis) Tuesday, February 19, 13 Fungi Reproduction Tuesday, February 19, 13 Fungi Reproduction • Mushrooms reproduce sexually by forming spores Tuesday, February 19, 13 Fungi Reproduction • Mushrooms reproduce sexually by forming spores • Haploid spores are produced by meiosis Tuesday, February 19, 13 Fungi Reproduction • Mushrooms reproduce sexually by forming spores • Haploid spores are produced by meiosis • Two spores combine to form a diploid cell Tuesday, February 19, 13 Fungi Reproduction Tuesday, February 19, 13 Fungi Reproduction • Mold reproduce sexually or asexually Tuesday, February 19, 13 Fungi Reproduction • Mold reproduce sexually or asexually • Produce asexual spores or two hyphae fuse together to mate Tuesday, February 19, 13 Characteristics of Bacteria Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria • prokaryotic Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria • prokaryotic • bacteria that survive in harsh condition (thermophiles, halophiles) Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria • prokaryotic • bacteria that survive in harsh condition (thermophiles, halophiles) • oldest forms of life Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria • prokaryotic • bacteria that survive in harsh condition (thermophiles, halophiles) • oldest forms of life Tuesday, February 19, 13 Eubacteria Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria Eubacteria • prokaryotic • prokaryotic • bacteria that survive in harsh condition (thermophiles, halophiles) • oldest forms of life Tuesday, February 19, 13 Characteristics of Bacteria bacteria are divided into two kingdoms Archaebacteria Eubacteria • prokaryotic • prokaryotic • bacteria that survive in • typical bacteria harsh condition (thermophiles, halophiles) • oldest forms of life Tuesday, February 19, 13 Characteristics of Protists Tuesday, February 19, 13 Characteristics of Protists • eukaryotic cells Tuesday, February 19, 13 Characteristics of Protists • eukaryotic cells • “junk drawer” or “catch-all” kingdom Tuesday, February 19, 13 Characteristics of Protists • eukaryotic cells • “junk drawer” or “catch-all” kingdom • organisms that don’t fit into a different kingdom Tuesday, February 19, 13 Animal-Like Protists Tuesday, February 19, 13 Animal-Like Protists • unicellular protozoans Tuesday, February 19, 13 Animal-Like Protists • unicellular protozoans • Ex: amoeba, paramecium Tuesday, February 19, 13 Plant-Like Protists Tuesday, February 19, 13 Plant-Like Protists • unicellular and/or contain pigments other than chlorophyll to photosynthesize Tuesday, February 19, 13 Plant-Like Protists • unicellular and/or contain pigments other than chlorophyll to photosynthesize • Ex: algae (red, brown) Tuesday, February 19, 13 Fungus-Like Protists Tuesday, February 19, 13 Fungus-Like Protists • fungi that are able to move for at least part of their life cycle Tuesday, February 19, 13 Fungus-Like Protists • fungi that are able to move for at least part of their life cycle • Ex: slime molds, downy mildews, water molds Tuesday, February 19, 13 Review Questions 1.
