1 CSLO5. Describe evidence for the evolution of cells, organelles and major metabolic pathways from early prokaryotes and how phylogenetic trees reflect evolutionary relationships. CSLO6. Compare characteristics and replication of acellular infectious agents (viruses and prions) with characteristics and reproduction of cellular infectious agents (prokaryotes and eukaryotes). PowerPoint Lecture Presentations prepared by Mindy Miller-Kittrell, North Carolina State University C H A P T E R 12 Characterizing and Classifying Eukaryotes
2 Eukaryotic microorganisms Include both human pathogens and organisms vital for human life Protozoa Fungi Algae Water molds Slime molds
3 Reproduction of Eukaryotes CONCEPT 12.1 Some show asexual reproduction Many reproduce sexually by forming gametes and zygotes More complicated than that in prokaryotes because Eukaryotic DNA packaged as chromosomes in the nucleus so nuclear division needed (1) Mitosis (2) Meiosis
4 CONCEPT 12.2 FACT 12.1 Mitosis 1) Cell partitions replicated DNA equally between two nuclei 2) Maintains ploidy of parent nucleus diploid produces diploid 3) Four phases Prophase Metaphase Anaphase Telophase Cytokinesis (cytoplasmic division) 1 cell becomes 2 cells
5 CONCEPT 12.3 FACT 12.2 Meiosis 1) Cell partitions replicated DNA unequally between 4 nuclei 2) diploid nuclei produce haploid daughter nuclei 3) Two stages meiosis I and meiosis II Each stage has four phases Prophase Metaphase Anaphase Telophase Cytokinesis (cytoplasmic division) 1 cell becomes 4 cells
6 MEIOSIS I Figure 12.1b The two kinds of nuclear division: mitosis and meiosis (1 of 2). Meiosis CONCEPT 12.3 Diploid nucleus (2n) DNA replication 1 Prophase I FACT 12.2 Tetrad (two homologous chromosomes, four chromatids) 2 Late prophase I Crossing over 3 Metaphase I 4 Anaphase I Chromosome (two chromatids) 5 Telophase I
7 MEIOSIS II Figure 12.1b The two kinds of nuclear division: mitosis and meiosis (2 of 2). Meiosis Chromosome (two chromatids) 5 Telophase I CONCEPT 12.3 FACT Prophase II 7 Metaphase II 8 Anaphase II 9 Telophase II Nuclear envelope Four haploid nuclei (1n)
8 Wall of parent cell Nuclei of daughter cells Vesicles forming cell plate Cleavage furrow plant cells = cell plate Bud Animal cells = cleavage furrow fungal cells = bud CONCEPT 12.4 Figure 12.2 Different types of cytoplasmic division. FACT 12.3
9 Schizogony Special type of division seen in some Cytokinesis is delayed multinucleated cells seen FACT 12.4 Merozoites Nucleus Schizont Multiple mitoses Cytokinesis
10 Protozoa CONCEPT 12.5 FACT 12.5 Diverse group defined by three characteristics 1) Eukaryotic 2) Unicellular 3) lack a cell wall So how do they survive in hypotonic environment? Some have contractile vacuoles that pump water out of cells For osmoregulation
11 FACT 1.3 Eukaryotic Microbes unicellular Protozoa (microanimals) Similar to animals in nutrient needs and cellular structure Live freely in water; some live in animal hosts Motile by means of cilia, flagella or pseudopodia Amoeba Pseudopods cell extensions that flow in direction of travel Blepharisma Cilia numerous short protrusions that propel organisms through its environment Peranema Flagella extensions of a cell that are fewer, longer, and more whiplike than cilia
12 Where do you find Protozoa moist environments (ponds, streams, lakes, and oceans) Very few are pathogens Morphology of Protozoa Great morphological diversity Some have two nuclei CONCEPT 12.6 Macronucleus (multiple copies of the genome) Micronucleus (single copy of the genome) Variety in number and kinds of mitochondria
13 Figure 12.6 Sexual reproduction via conjugation in ciliates. Diploid micronuclei Compatible mates 1 Mates couple. 2 Meiosis of micronuclei produces four haploid micronuclei in each. 3 Three micronuclei in each disintegrate; the remaining two replicate by mitosis. Haploid micronuclei 4 Mates each swap one micronucleus. Haploid micronucleus (1n) Macronucleus (50n) Diploid micronucleus (2n) 5 Partners separate. 9 Three cytokineses partition a macronucleus and a micronucleus into each of four daughter cells. 8 Original macronucleus disintegrates. Four micronuclei become macronuclei by replicating chromosomes numerous times; four micronuclei remain micronuclei. 7 Three mitoses without cytokinesis produce eight micronuclei. 6 The two different micronuclei fuse to form diploid micronucleus.
14 CONCEPT 12.7 The life cycle of Protozoa has different stages Motile feeding stage called a trophozoite Resting stage called a cyst
15 Classification of Protozoa Classification of protozoa has shifted over the years Revised and updated based on 18s rrna sequences One current scheme groups protozoa into six groups 1) Parabasala 2) Diplomonadida 3) Euglenozoa 4) Alveolates 5) Amoebozoa 6) Rhizaria
16 Classification of Protozoa 1) Parabasala FACT 12.6 Contain Golgi body like structure called a parabasal body Figure 12.7 Trichonympha acuta, a parabasalid with prodigious flagella. Important parabasalids Trichonympha Trichomonas Trichomonas vaginalis, which causes a sexually transmitted disease in humans Hydrogenosomes (like mitochondria) typical mitochondria Is absent
17 Classification of Protozoa 2) Diplomonadida (2 nuclei- double cells) FACT 12.7 Lack mitochondria modified mitochondria-like organelles called mitosomes in the cytoplasm Have two equal-sized nuclei and multiple flagella Giardia causes Giardiasis(beaver fever)
18 3) Euglenozoa Two groups 3a) Euglenids 3b) Kinetoplastids FACT 12.8 Mitochondria have disk-shaped cristae 3a) Euglenids Photoautotrophic Both animal and plant-like features Chloroplast Flagella, Eyespot
19 3) Euglenozoa FACT b) Kinetoplastids Have multiple copies of mitochondrial DNA called a kinetoplast Kinetoplast Some kinetoplastids are pathogenic Trypanosoma Trypanosomes infect a variety of hosts and cause various diseases, including the fatal human diseases sleeping sickness, caused by Trypanosoma brucei
20 sleeping sickness, caused by Trypanosoma brucei
21 4) Alveolates Have membrane-bound cavities called alveoli FACT Divided into three subgroups 4a) Ciliates 4b) Apicomplexans 4c) Dinoflagellates
22 4a) Ciliates FACT Use cilia to move themselves or water All are chemoheterotrophs and have two nuclei Balantidium is the only ciliate pathogenic to humans
23 4b) Apicomplexans Chemoheterotrophic pathogens of animals Obligate endoparasites FACT Complex of organelles allow them to penetrate host cells apical complex burrow Plasmodium and Toxoplasma cause disease in humans
24 Plasmodium
25 4c) Dinoflagellates FACT Unicellular microbes with photosynthetic pigments Historically classified as algae Motile dinoflagellates have two flagella
26 Dinoflagellates forms Large proportion of freshwater and marine plankton FACT Planktons especially phytoplankton support foodchain and life
27 Many dinoflagellates are bioluminescent Abundance in marine water is one cause of red tides some red tides kill because dinoflagellates produce neurotoxins
28 5) Amoebozoa FACT Amoebae with lobe-shaped pseudopods and no shells Includes some human pathogens Entamoeba Slime molds are now classified as amoebozoa 1) Plasmodial slime molds 2) Cellular slime molds
29 FACT Plasmodial slime molds Cellular slime molds
30 6) Rhizaria - Amoebae with shells that move and feed with thread-like pseudopods FACT Foraminifera Have ornate shells of calcium carbonate Both constitute the marine zooplankton Radiolaria Have ornate shells of silica
31 Fungi Chemoheterotrophic acquire nutrients by absorption Have cell walls typically composed of chitin Do not perform photosynthesis - Lack chlorophyll The Significance of Fungi Decomposers Decompose dead organisms and recycle their nutrients Most are saprobes (living on dead) CONCEPT 12.8 FACT 12.16
32 FACT Help plants absorb water and minerals mycorrhizae
33 mycelium hyphae Fungus has 2 basic body shapes 1) Hyphae (moldlike shape) 2) Single celled (yeastlike shape) 3) Mixed (dimorphic or both)
34 The Significance of Fungi Mold (hyphae) Produce antibiotics and other drugs Penicillium
35 The Significance of Fungi Saccharomyces (Yeast) single celled Used for food and in manufacture of foods and beverages
36 30% of fungus cause diseases of plants, animals, and humans Can spoil fruit, pickles, jams, and jellies Candida albicans is an opportunistic pathogenic yeast that is a common member of the human gut flora and also causes yeast infection. Candida albicans (a type of Yeast) mixed
37 Fungi- Photosynthetic Partnership Lichens Partnerships between 1) Fungi - provides nutrients, water, and protection 2) Photosynthetic microbes - provides carbohydrates and oxygen Create soil from weathered rocks Eaten by many animals CONCEPT 12.9 Abundant throughout the world Grow in almost every habitat
38 Algae Simple, eukaryotic phototrophs CONCEPT Carry out oxygenic photosynthesis using chlorophyll a Most are aquatic Can have different morphologies Unicellular Colonial Simple multicellular bodies called thalli
39 Classification of Algae CONCEPT Classified based on different features Differences in photosynthetic pigments Storage products Cell wall composition Various groups Division Chlorophyta Kingdom Rhodophyta Phaeophyta Chrysophyta FACT 12.18
40 Division Chlorophyta (green algae) FACT Most are unicellular and filamentous Spirogyra Cell wall - cellulose Kingdom Rhodophyta (red algae) Cell wall - Agar unicellular red algae Thermoacidophilic found in Yellowstone geysers
41 Phaeophyta (brown algae) FACT Cell walls composed of cellulose and alginic acid Alginic acid is used medically and as a thickening agent
42 Chrysophyta (golden algae, yellow-green algae, and diatoms) FACT Most are marine algae - phytoplankton Diatoms silica frustules Cell wall cellulose and silica
43 Water Molds CONCEPT Differ from fungi in several ways Have tubular cristae in their mitochondria Cell walls are of cellulose instead of chitin Decompose dead animals and return nutrients to the environment Recyclers in Water FACT Some species are pathogens of crops caused the Irish potato famine
44 Other Eukaryotes of Microbiological Interest: Parasitic Helminths Parasitic worms have microscopic infective and diagnostic stages
45 CONCEPT FACT Other Eukaryotes of Microbiological Interest: Vectors Arthropod vectors are animals that carry pathogens 1) Arachnids (Adult have four pairs of legs) Ticks are the most important arachnid vectors 2) Insects (Adult have three pairs of legs and three body regions) Include Fleas, Lice, Flies and Mosquitoes (most important)
