Kingdom Eubacteria

Question 1

What kingdom accounts for most bacteria?

Answer 1

Eubacteria

Question 2

How is eubacteria characterized?

Answer 2

By the presence of a protein-carbohydrate complex called peptidoglycan in their cell walls.

Question 3

What does peptidoglycan’s function do?

Answer 3

To main the shape of the cell and maintain osmotic pressure, meaning it lets in just the right amount of water and ions that the cell needs.

Question 4

What are members of Eubacteria able to form? What does this allow them to do?

Answer 4

• spores

- allows them to remain dormant over years

Question 5

What are the three shapes Eubacteria come in?

Answer 5

• Basilla
• Cocci
• Spirella

Question 6

Eubacteria can be classified in as many as__different phyla?

Answer 6

12

Question 7

Cyanobacteria:
Shape?
Gram Reaction?
Nutrition and Lifestyle?
Example(s)?
Produced\_\_\_\_inearly Earth which gave rise to\_\_\_\_; thrive on\_\_\_\_\_and\_\_\_\_which causes\_\_\_\_\_to bloom in bodies of\_\_\_\_; when they die\_\_\_\_bacteria cause them to decomposeand \_\_\_\_\_is depleted from the bodies of\_\_\_\_.

Answer 7

Shape: Basilli, cocci
Gram Reaction: gram negative
Nutrition and Lifestyle: Photosynthetic; aerobic
Example(s): Produced oxygen in early Earth which gave rise to an atmosphere; thrive on nitrates and phosphates which causes bacteria to bloom in bodies of water; when they die heterotrophic bacteria cause them to decompose and oxygen is depleted from the body of water.

Question 8

Spirochetes:
Shape?
Gram Reaction?
Nutrition and Lifestyle?
Example(s)?

Answer 8

Shape: Spiral
Gram Reaction: gram negative
Nutrition and Lifestyle: heterotrphiic; anaerobic and aerobic
Example(s): causes the STI syphilis

Question 9

Gram Positive:
Shape?
Gram Reaction?
Nutrition and Lifestyle?
Example(s)? the bacteria used to make\_\_\_\_; they are found in your\_\_\_ \_\_\_ and \_\_\_ where they slow the growth of \_\_\_\_\_bacteria; some are found in the\_\_\_\_and produce\_\_\_\_.

Answer 9

Shape: bacilli, coccus
Gram Reaction: mostly gram positive
Nutrition and Lifestyle: autotrophic, heterotrophic; anaerobic, aerobic
Example(s): the bacteria used to make yogurt; they are found in your oral cavity and gut, where they slow the growth of disease-causing bacteria; some are found in the soil and produce antibiotics.

Question 10

Proteobacteria:
Shape?
Gram Reaction?
Nutrition and Lifestyle?
Example(s)? \_\_\_lives in human guts and helps to make\_\_\_\_; responsible for \_\_\_ \_\_\_ caused by \_\_\_\_.

Answer 10

Shape: bacilli, cocci, spirella
Gram Reaction: gram negative
Nutrition and Lifestyle: heterotrophic and autotrophic; anaerobic and aerobic
Example(s): E. Coli lives in human guts and helps us to make vitamin K; responsible for food poisoning caused by salmonella.
