Question

'Some organism can be poisoned by oxygen, although it is considered as life sustaining gas'. Do you agree with the statement. Justify your answer.

Answer 1

Answer:

Yes, I agree with the statement.

Explanation:

There are organisms which do not require oxygen to function. Such organisms are usually microorganisms and are called as anaerobic. Some of these organisms can survive in the presence of oxygen while others will get killed in the presence of oxygen. So we can say that oxygen might be toxic for some organisms. Hence, the above statement can be considered to be true.

Answer 2

Microorganisms that can get poisoned by oxygen are called anaerobic organisms. There are bacteria that sustain and thrive in specifically anaerobic environments.  

Explanation:

• Organisms that cannot thrive in oxygen can get killed in its presence.
• Though for the majority of living organisms oxygen is vital for their survival but strangely for certain algae and bacteria oxygen can prove to be disastrous.
• Organisms that cannot survive in the presence of oxygen are – Fusobacterium, Bacteroides, Clostridium, Porphyromonas, Veillonella, Prevotella and Propionibacterium.
