Consider the following statements :
1. Some microorganisms can grow in environments with temperature above the boiling point of water.
2. Some microorganisms can grow in environments with temperature below the freezing point of water.
3. Some microorganisms can grow in highly acidic environment with a pH below 3.
How many of the above statements are correct?
Explanation
The answer is (c). All three statements are correct.
“- Thermophiles: A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F).
– Psychrophiles or cryophiles are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from −20 °C (−4 °F) to 20 °C (68 °F).
– Acidophiles are organisms that can withstand and even thrive in acidic environments where the pH values range from 1 to 5.”
