Chapter 23 Bacteria

All bacteria belongs to kingdom ________

bacteria

List the 3 phyla of Archaebacteria in this kingdom

halogens, methanogens, thermoacidophiles

List 3 diseases that are caused by bacteria

ecoli, chagas disease, malaria

Explain difference between prokaryote and eukaryote AND tell which one the bacteria belongs in

prokaryotes don't have a membrane bound nucleus, eukaryotes do. Bacteria are prokaryotes

What type of bacteria might you find in a deep oceanic volcanic vent?

thermoacidophiles

What do we call a bacterium that uses sunlight as an energy source?

photoautotroph

How long is binary fission in bacteria?

20-60 minutes

Rapid increase in population of bacteria

bloom

group that contains spiral shaped organisms

spirochete

Process by which gaseous nitrogen is converted

nitrogen fixation

Sticky substance that allows bacteria to attach to surfaces

glycocalyx

Use energy from chemical reactions

chemoautotroph

Type of reproduction in which genetic information is exchanged

conjugation

Short strands of DNA

plasmid

Dormant cell enclosed by a tough coating

endospore

An organism that causes a disease

pathogen

Specialized cells that convert nitrogen from the atmosphere into a form that the organism can use

heterocyst

Phylum of bacteria that are adapted to harsh environments in which they live

archaebacteria

Protective layers around the cell walls of bacteria

capsule

Organisms, which use sunlight as its source of energy

photoautotroph

Bacteria that have a protective outer covering which make them difficult to treat with antibiotics

Gram negative bacteria

Bacteria that use carbon dioxide and hydrogen to form methane and water

methanogen

Describe the process of conjugation

2 bind together to make one. Genetic info was exchanged

Bacteria have 3 shapes. Name the 3 bacteria and give their shape

cocci circle, bacilli rod, spirella spiral

Give an example of the following kingdoms: Plantae, Animalia, Protista, Archaebacteria

plants, animals, amoeba, archaea

Poisons which are secreted into the area surrounding the bacteria

exotoxin

A test that uses a series of dyes to stain bacteria cell walls

gram stain

Bacteria that cannot survive in the presence of oxygen

obligate anaerobe

Cyanobacterium

blue green bacteria

Protein strands that attach bacteria to other objects

pili

Chemicals that are capable of inhibiting growth of some bacteria

antibiotics

Type of asexual reproduction

binary fission

Archaebacteria that live in places that are very hot and very acidic

thermoacidophiles

Poisonous substances that are found in the cell walls of bacteria

endotoxin

Bacteria that cannot survive without oxygen

obligate aerobe

Organism that produces its own food

autotroph

Bacteria that can live with or without oxygen

facultative anaerobe

Class of bacteria that contains rod-shaped organisms that form branched filaments

actinomycetes

List the levels of classification in order

kingdom, phylum, class, order, family, genus, species
