Detailed explanation-1: -Proper cortex formation is needed for dehydration of the spore core, which aids in resistance to high temperature. A germ cell wall resides under the cortex. This layer of peptidoglycan will become the cell wall of the bacterium after the endospore germinates.

Detailed explanation-2: -The formation of endospores in some bacteria also helps them in their survival. The endospore can survive in extreme conditions and do not germinate until the conditions have become normal for the bacteria. The bacteria that live in difficult conditions have evolved to survive in those conditions.

Detailed explanation-3: -The cortex is what makes the endospore so resistant to temperature. The cortex contains an inner membrane known as the core. The inner membrane that surrounds this core leads to the endospore’s resistance against UV light and harsh chemicals that would normally destroy microbes.

Detailed explanation-4: -Structure Of Endospores Endospores have a unique cellular structure. It is surrounded by an outer covering which is proteinaceous. This coating provides enzymatic and chemical resistance to the spore. It is lined by a thick inner layer consisting of specialized peptidoglycan which forms the cortex.

Detailed explanation-5: -Spores are highly resistant to a wide variety of physical stresses such as: wet and dry heat, UV and gamma radiation, oxidizing agents, chemicals, and extremes of both vacuum and ultrahigh hydrostatic pressure.
