Question 0

What is the major characteristic of the Archaebacteria and the Eubacteria?

Answer 0

The contain ONLY prokaryotic organisms which means they do NOT have a true nucleus with a membrane surrounding the genetic material and the organelles are not surrounded by a membrane

Question 1

List three ways that archaebacteria are different from eubacteria

Answer 1

• archaebacteria’s cell walls lack a certain compound
• parts of archaebacteria’s DNA are more similar to eukaryotes than to other bacteria
• many archaebacteria live in extreme environments

Question 2

What are the three shapes bacteria can have

Answer 2

Sperical ,called coccus
Rod-shaped ,called bacillus
Spiral ,called spirillum

Question 3

Do all bacteria have a cell membrane

Answer 3

Yes

Question 4

What are three things bacteria need to survive

Answer 4

A great deal of food, they need oxygen to I grow, they need a specific temperature to live in

Question 5

List three human foods that bacteria help produce

Answer 5

• yogurt
• cheese
• dill pickles

Question 6

What is a virus made of

Answer 6

A nucleic acid core with protein coat

Question 7

Why is the virus not classified into a kingdom

Answer 7

It doesn’t have a cell membrane

Question 8

What are two things that can protect your body from viruses

Answer 8

Vaccinations, good hygiene

Question 9

Like all cells bacteria is surrounded by what

Answer 9

A cell membrane a cell wall and a capsule

Question 10

True or false: bacteria are Prokaryotic?

Answer 10

True

Question 11

The action of a virus is called what

Answer 11

Lytic cycle

Question 12

How do bacteria reproduce?

Answer 12

Binary fission

Question 12

What do all bacteria have?

Answer 12

Cell membrane

Question 13

What is a latent virus?

Answer 13

A virus that remains inactive inside a host cell

Question 14

Are viruses living organisms?

Answer 14

No

Question 15

What is a coccus?

Answer 15

Spherical bacteria

Question 16

Give two examples of decomposed organisms?

Answer 16

Bacteria and fungi

Question 17

What two kingdoms contain prokaryotic organisms?

Answer 17

Archaebacteria and Eubacteria

Question 18

Do most bacteria cause disease in humans?

Answer 18

Although many do cause human diseases most do not. They are important decomposed organisms breaking down dead organic material to return nutrients to the food chain

Question 19

Does antibiotic resistant bacteria support evolution?

Answer 19

No

Question 20

What does prokaryotic mean?

Answer 20

There is no true nucleus with a membrane surrounding it and organelles are not surrounded by a membrane. Genetic material is clumped together in a nuclear area

Question 21

How do most bacteria move?

Answer 21

With flagella

Question 22

What is Cyanobacteria?

Answer 22

Eubacteria that resembles algae because of its blue green color

Question 23

What is binary fission?

Answer 23

DNA is doubled by DNA replication. The cell membrane then pinches in two until the cell splits causing two daughter cells.

Question 24

If bacteria grow so quickly why don’t they cover the whole earth?

Answer 24

Because they need very specific conditions to grow in. Lack of food or water, insufficient oxygen and waste build up prevent colonies from getting too big.
