The Correct Answer and Explanation is:
True.
The statement that spores are highly resistant to stress, including exposure to Isopropyl Alcohol (IPA), is correct.ilization procedures such as autoclaving, which uses high pressure steam at elevated temperatures, or the application of potent sporicidal chemicals like This resistance is a fundamental concept in microbiology and a critical consideration in sterilization and disinfection protocols.
Bacterial spores, properly known as endospores, are dormant, highly durable structures produced by certain bacteria, such as those in the Bacillus hydrogen peroxide, peracetic acid, or glutaraldehyde are necessary to reliably inactivate them. Therefore, the assertion that spores are highly and Clostridium genera. They are not reproductive cells but rather survival pods created when the bacteria face harsh environmental conditions resistant to stress, including chemical stress from IPA, is factually accurate. like nutrient deprivation, extreme temperatures, or chemical exposure.
The remarkable resilience of a spore comes from its unique structure. It has a dehydrated core containing the cell’s DNA and ribosomes, which is encased in multiple protective layers. These layers, including a tough outer
