Biodiversity- (5) Bacteria VS Archea

Question 1

What 3 shapes can both bacteria and archea be classifies as

Answer 1

Cocci (round) Bacilli (rods) spirillium (spiral)

Question 2

How do archea eat?

Answer 2

Methanogenisis

Question 3

Whats methanogenisis

Answer 3

Biolgoical process used to create energy, has methane as a byproduct (CH4)

Question 4

How do Bacteria eat?

Answer 4

Photosynthesis- sunlight into energy

Question 5

Difference between habitat between archea and bacteria

Answer 5

While both can survive in aerobic and anearobic conditions, they differ between their ability to tolerate extreme conditions.

Question 6

Whats a mesophile

Answer 6

Bacteria are mesophiles- they need MODERATE conditions

Question 7

Whats an extremophile

Answer 7

Archea are extremophiles- they need EXTREME conditions

Question 8

What are the 3 catagories of extremophiles?

Answer 8

Thermophiles, Acidophiles, Halophiles

Question 9

Whats a thermophile?

Answer 9

Heat lovers thrive in extremely hot conditions

Question 10

Whats an acidophile

Answer 10

Acid lovers thrive in acidic low ph environments

Question 11

Whats a halophile

Answer 11

Salt lovers thrive in salt lakes and the dead sea

Question 12

How do both bacteria and archea replicate

Answer 12

Binary fission. Asexual, DNA duplicates, cytoplasm divides at septum, 2 identical daughter cells created.

Question 13

What do bacteria do in less favourable conditions?

Answer 13

conjugation, and the creation of endospores

Question 14

What is meant by bacterial conjugation

Answer 14

Passing genetic material from one cell to another in hopes of spreadin and saving atleast some genetic material and diversity

Question 15

What is the creation of endospores

Answer 15

Hard walled structures are formed that resist extremes, and when favourable conditions return endospores germinate into active bacteria. Endospores cannot survive forever.
