KINGDOM MONERA (BACTERIA) F E B R UA RY 2 5 2 0 1 6 LEARNING OBJECTIVES Identify and label structures of a generic Monera Identify and Describe the four criteria through which Monera are classified Describe the ways in which Monera

obtain/metabolize energy Describe the three ways Monera reproduce LEARNING OBJECTIVES Why study Bacteria ?

LEARNING OBJECTIVES WHAT WE LOOK LIKE Structure | Classification | Energy | Growth/Reproduction WHAT WE LOOK LIKE All Monera are unicellular and prokaryotic No nucleus. DNA or

RNA and ribosomes floating in cytoplasm. Structure | Classification | Energy | Growth/Reproduction WHAT WE LOOK LIKE Cell membrane made of lipids Cell wall made of peptidoglycan to protect cell

Flagellum to move Structure | Classification | Energy | Growth/Reproduction Structure | Classification | Energy | Growth/Reproduction ACTIVITY TIME! Please arrange yourselves into groups of 3 When you have a group

ACTIVITY TIME! 1 Coloured sheet 3 fact sheets 1 fact sheet per person Puzzle out which bacteria is which HOW WE ARE CLASSIFIED

Cocci Round Spirilla Bacilli 1. Shape 2. Cell Wall 3. Bacterial Movemen t

4. DNA/RNA Shaped Spiral and like a rod shaped spherica (or (looks like l

sausage) pasta) Structure | Classification | Energy | Growth/Reproduction HOW WE ARE CLASSIFIED Clustering Behaviour can also help with classifying bacteria Some bacteria

form chains, Structure form | Classification others 1. Shape 2. Cell Wall 3. Bacterial Movemen t 4. DNA/RNA

| Energy | Growth/Reproduction HOW WE ARE CLASSIFIED Hans Christian Gram was staining bacteria with crystal violet. He realized some retained the crystal violet and

Structure | Classification others did not. 1. Shape 2. Cell Wall 3. Bacterial Movemen t 4. DNA/RNA | Energy | Growth/Reproduction

HOW WE ARE CLASSIFIED 1. Shape 2. Cell Wall 3. Bacterial Movemen t 4. DNA/RNA Structure | Classification | Energy | Growth/Reproduction HOW WE ARE CLASSIFIED Gram-positive:

cells that can retain the crystal violet (purple) Gram-negative: cells that cant retain crystal violet (pink) 1. Shape 2. Cell Wall 3. Bacterial

Movemen t 4. DNA/RNA Structure | Classification | Energy | Growth/Reproduction HOW WE ARE CLASSIFIED Bacteria with a thick peptidoglycan cell wall could

retain the crystal violet. Bacteria with a thin Structure | Classification peptidoglycan 1. Shape 2. Cell Wall 3. Bacterial Movemen

t 4. DNA/RNA | Energy | Growth/Reproduction HOW WE ARE CLASSIFIED Flagella: whiplike projection that helps bacteria move Slime: glide on slime secretion (like a slug)

1. Shape 2. Cell Wall 3. Bacterial Movemen t 4. DNA/RNA Structure | Classification | Energy | Growth/Reproduction No movement

HOW WE ARE CLASSIFIED The genetic makeup of species is generally unique. Probably the most specific identificatio

Structure | Classification 1. Shape 2. Cell Wall 3. Bacterial Movemen t 4. DNA/RNA | Energy | Growth/Reproduction What is the

shape of this bacterium? Is it gramnegative or gram positive? Structure | Classification | Energy | Growth/Reproduction Structure | Classification | Energy | Growth/Reproduction HOW WE TRAP ENERGY Phototrophic Autotrophs:

Monerans that trap the energy of the sun Cyanobacteri a Structure | Classification | Energy | Growth/Reproduction HOW WE TRAP ENERGY Chemotrophic Autotrophs: Monerans that trap

the energy of the inorganic molecules (e.g. hydrogen sulfide, nitrites, ammonia) Structure | Classification | Energy | Growth/Reproduction HOW WE TRAP ENERGY Chemotrophic Heterotrophs (aka heterotrophs)

Monera that trap the energy of the organic molecules (e.g. salmonella) Phototrophic Heterotrophs: Monera that Structure | Classification | and Energy | Growth/Reproduction can photosynthesize
