Question

Explain whether or not you think all bacteria need oxygen in order to grow.

a) Yes, all bacteria require oxygen for growth.

b) No, some bacteria can grow without oxygen.

c) Bacteria only need oxygen in specific environments.

d) Bacteria growth is not related to oxygen levels.

Answer 1

No, some bacteria can grow without oxygen. Bacteria can be classified into different categories based on their oxygen requirements for growth.

Step-by-step explanation:

No, some bacteria can grow without oxygen. Bacteria can be classified into different categories based on their oxygen requirements for growth. Obligate aerobes require oxygen for growth and cannot grow without it. On the other hand, obligate anaerobes are killed by oxygen and can only grow in the absence of oxygen. Facultative anaerobes can grow in the presence or absence of oxygen, while aerotolerant anaerobes are indifferent to the presence of oxygen. Microaerophiles require a minimum level of oxygen for growth.
