100
What are the two kingdoms of prokaryotes?
Eubacteria and Archaebacteria
100
The whip like structure that propels some bacteria.
What is the flagellum
100
What is the most common way for bacteria to reproduce?
Binary fusion
100
Obligate aerobic bacteria need what to survive?
Oxygen
100
The two parts that comprise a virus.
What is the capsid and the DNA (or RNA)
200
Which prokaryote kingdom is larger?
Eubacteria
200
What are the shapes associated with bacteria.
Rods (Bacilli), Spheres (Cocci), Spirals (Spirilla)
200
What is an endospore?
A spore formed when a bacteria produces a thick wall that encloses its DNA.
200
What is the difference between facultative and obligate anaerobic bacteria?
Oxygen will kill obligate anaerobic bacteria.
200
How do viruses attach to cells?
What is receptors on the cell surface.
300
What is the difference between prokaryotic cells and eukaryotic cells?
Lack a nucleus, membrane bound organelles, smaller than eukaryotic cells.
300
All bacteria are dangerous?
False
300
What is the structure used in conjugation.
The pilus
300
How does a chemoautotroph get energy?
Gets energy directly from chemical reactions involving inorganic molecules.
300
Why are viruses not considered alive.
What is they lack respiration and cannot replicte except within a cell.
400
What is the difference between the two kingdoms of bacteria?
Archaebacteria lack peptidoglycan in their cell membranes.
400
Bacteria that break down dead material are called?
Decomposers
400
Describe conjugation.
A hollow bridge between two cells transfers genetic material.
400
What does a chemoheterotroph need to consume to survive?
Organic molecules
400
The steps of the lytic cycle.
What are attachment, insertion, replication, release.
500
How can you classify prokaryotes (4 ways)?
Shape, cell walls, movement, and the way they obtain energy.
500
How do nitrogen fixing bacteria help plants?
They turn nitrogen into a useable form for plants.
500
What is binary fusion?
Asexual reproduction, bacteria doubles its size and replicates its DNA. Then divides in half creating two cells.
500
What is the difference between a photoautotroph and a photoheterotroph?
Autotrophs create their own energy and carbon. Heterotrophs need organic molecules for a carbon source.
500
The lysogenic cycle.
What are virus attaches, inserts genetic material, incorporates into host genes, host replicates, viral DNA enters the lytic cycle.
