How are eubacteria and archaebacteria different

makeup of their cell walls

Are eubacteria or archaebacteria thought to be the ancestors of eukaryotes

archeabacteria

Methanogens belong to which kingdom?

Archaebacteria

What shape is coccus?

round

What color do Gram-positive bacteria turn when treated with Gram Stain?

violet

What are bacilli, cocci, and spirilla?

shapes of prokaryotes

Which characteristics are used to identify prokaryotes?

cell shape, way the prokaryote moves, and way prokaryotes obtain energy

Where are you likely to find a photoautotroph?

near the surface of lakes, streams, and oceans

How do chemoautotrophs obtain energy?

directly from inorganic molecules

How do most prokaryotes obtain energy?

heterotrophs

What does Gram staining tell you about the cell?

what kind of cell wall a prokaryote has

Why are bacteria sometimes called "nature's recyclers"?

break down nutrients in dead matter

What type of roles deos bacteria have in the environment?

carrying out photosynthesis, fixing nitrogen, recycling nutrients

bacteria that break down nutrients in dead matter into simpler substances taht are taken up by plant roots are called

decomposers

Soybeans, rhizobium, and nodules on roots are all involved in

nitrogen fixation

Human uses of bacteria

clean up small oil spills, mine minerals from the ground, synthesize drugs

Which kingdom lives in extreme environments such as Utah's Great Salt Lake?

archaebacteria

Which kingdom reacts to Gram staining?

eubacteria

Can bacteria be used to synthesize drugs through genetic-engineering techniques

yes

Which group of bacteria can carry out photosynthesis in a manner similar to that of plants?

photoautotrophs

the process of converting nitrogen to a form plants can use is called

nitrogen fixation

in the human intestines, bacteria help the body make what substance

vitamins

list the four factors that are used to identify prokaryotes

their shape, the way they move, chemical nature of their cell walls, and the way they obtain energy

describe 3 ways in which humans use bacteria

produce food, mining minerals, clean up oil spills, clean up sewage, remove waste from water, synthesizing drugs and chemicals
