Diversity

Archaea

archaea

4.Thermopiles

Live in extremely hot water (above 100 c)

Found in hot springs inYellowstone National Park,and deep sea vents

3.Acidophiles

Can live at Ph of 0

Found in volcanic craters and mine drainage lakes

2.Halophiles

Live in very salty water

Found in the Dead Sea, Great Salt Lake,

1.Methanogens

Live in anaerobic environment (no oxygen}

Obtain energy by changing H2 and CO2 intomethane gas

Found in swamps, marshes, sewage treatmentplants, digestive tracts of animals, landfills

Bacteria

bacteria

4. DEATH PHASE:

wastesbuild up and food

sources are depleted

Bacteria start to die

3. STATIONARY PHASE:

more and more bacteriaare competing

dwindling food supply

Growth stabilizes

2. LOG PHASE:

rapidbacterial growth atan exponential rate

1. LAG PHASE:

growthis slow as bacteriaacclimates to foodand nutrients

2. Gram-Positive Bacteria:

Have a thick protein layeron cell wall and will stain purple

1. Gram-Negative Bacteria:

Have a thin protein layeron cell wall and will stain pink

2. Conjugation

Sexual Reproduction

Transfer of geneticmaterial (plasmids)

Sex pilus is used to sharegenetic information

1. Binary Fission

Asexual Reproduction

Produces 2 geneticallyidentical cells

Groupings: (prefix)

Diplo – pairs

Staphylo – clusters

Strepto – chains

Shapes:

Cocci – round

Bacilli – rod-shaped

Spirilli – spiral-shaped

can be helpful or pathogenic

Contain plasmids: small,circular pieces of DNA

autotroph (produces own food

heterotroph (must obtain food

Bacteria are prokaryotes

mostly unicellular organisms

mesophilic:live in environments withmoderate condition

Genetic material iscontained in nucleoid

Genetic material iscontained in nucleoid

Viruses

• Lysogenic Cycle:

Virus’s genetic material enters the host

cell’s nucleus and inserts itself into the

host’s chromosomes called a provirus

it is copied every timethe host cell divides

Viral DNA staysdormant (inactive

• Lytic Cycle:

Once virus is replicatedand assembled

host cellruptures releasing

new virus into surroundings

Host cell is destroyed

2. Narrow Host Range

infects only 1-3 species/cells

Viruses cannot reproduce on their own

onlyreplicate when they are in a living host cell

1. Broad Host Range:

infects many species/cells

Acellular  non-living

Very small organisms (20-400 nm)

DNA or RNA core

Capsid: protein coatsurrounding the core

Sometimes have anenvelope surroundingthe capsid

Viruses are generally selective: specific virusesonly enter specific hosts, cells or tissues

Host range: thenumber of host

species, tissues orcells that can beinfected by a virus

Eukarya

Fungi

Club Fungi

multicellular

mushrooms,puffballs

sexual basiospore from basidium

mycelium

Sac Fungi

largest group

powdery mildews on leaves,struffles

reproduction sexual

bearing asci small finger-like sacs

single-celled yeasts reproduce asexually by budding

Zygospore Fungi

multicellular (land)

mostly terrestrial

common moulds bread mould

reproduces asexually

produce zygospore

remains dormant until favorable conditions return

Chytrids

mostly unicellular

Aquatic

spores have flagella

parasitic or live on decaying organisms

live in soil

causes potato wart disease
