Question 1

What shapes do bacteria exists in?

Answer 1

Coccus 
Bacillus 
Coccobacillus (Coccus + Bacillus) 
Vibrio 
Spirochete 
Spirillum

Question 2

What are endospores?

Answer 2

Some bacterial species are able to form endospores through sporulation.
It forms a protective layer to protect the genetic material of the cell
Endospores are formed during harsh environments
They are resilient to harsh conditions hence vegetative cell would not be killed off easily

Question 3

What are the things to take note of when typing out the scientific name of a microorganism?

Answer 3

Should always be italicized
First letter of genus should be capitalized
First letter of species should be in lowercase

Question 4

What are the things to take note of when writing out the scientific name of a microorganism?

Answer 4

Should always be underlined separately (full stop should not be underlined, short form)
First letter of genus should be capitalized
First letter of species should be in lowercase

Question 5

Why are endospores more resistant than vegetative cells?

Answer 5

Endospores have a high content of a specific protein that protects the bacterium’s genetic information
Vegetative cells do not have this specific protein, bacterium’s genetic information is not protected, gets killed off easily

Question 6

Can endospores undergo cell division?

Answer 6

No
Endospores need to undergo germination to form a vegetative cell first, in favourable conditions
Then the vegetative cell will undergo cell division
