NURSING ANM AND GNM

Detailed explanation-1: -It allows the bacterium to produce a dormant and highly resistant cell to preserve the cell’s genetic material in times of extreme stress. Endospores can survive environmental assaults that would normally kill the bacterium.

Detailed explanation-2: -Endospores are resistant to the chemical agents, e.g., triphenylmethane dyes, and can even protect the bacterial cells against ultraviolet radiation, extreme pH gradients, drought, and nutrition depletion.

Detailed explanation-3: -Several features in particular help to make endospores resistant to environmental stress. They have a low water content, unusual proteins and a tough spore coat that is not present in the mature bacterial cells.

Detailed explanation-4: -Endospores can survive without nutrients. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants. They are commonly found in soil and water, where they may survive for long periods of time. Bacteria produce a single endospore internally.

Detailed explanation-5: -Bacterial endospores are simplified forms of the bacteria, consisting of the DNA genome, some small amount of cytoplasm, and a specialized coating that confers resistance to heat, radiation, and other harsh external conditions.
