Answer 3

internal structure made by bacteria

Question 4

Structure of Endospores

Answer 4

a cell’s chromosome is wrapped in several protective layers of protein

Question 5

Dormant

Answer 5

metabolically inactive, do not undergo cell division

Question 6

Why are endospores made?

Answer 6

it’s a way for bacteria to hide when growth conditions are bad
(bacterial hibernation)

Question 7

How are endospores made?

Answer 7

by endospore-forming bacteria that goes through cell division

Question 8

What happens to endospores after they’re made?

Answer 8

they remain inside the bacteria unit it dies, then it’s released

Question 9

Germination

Answer 9

endospore revives and starts growing into a cell

When does an endospore germinate?

Answer 10

when growth conditions improve
