false endospore
An Endospore.
An endospore is a dormant, tough, and non-reproductive structure formed by certain bacteria. It consists of a core containing the bacterial DNA and ribosomes, surrounded by protective layers of protein and dipicolinic acid. This structure enables the bacteria to survive harsh conditions like high heat, lack of nutrients, and exposure to chemicals.
The protective resting stage of bacteria is known as endospore formation. During unfavorable environmental conditions, some bacteria can undergo sporulation to form endospores, which are highly resistant structures that protect the bacterial DNA and allow survival until conditions improve. Endospores can resist extreme heat, desiccation, and chemicals, making them difficult to kill.
The thick protective coat around an endospore is primarily composed of peptidoglycan layers, along with other proteins and enzymes that help protect the endospore from environmental stresses such as heat, desiccation, and chemicals. This complex structure allows endospores to remain dormant and highly resistant to adverse conditions.

resting or dormant type of cell that is highly resistant to environmental extremes (heat, dessication, oxygen, radiation, disinfectants).
An Endospore.
Endospore formation, or sporulation, is a survival mechanism used by some bacteria to protect their genetic material during harsh conditions. The process involves a series of steps where a bacteria cell produces a thick-walled structure called an endospore, within which the DNA and other essential cellular components are enclosed. This endospore can withstand extreme conditions such as heat, radiation, and chemicals, allowing the bacteria to remain dormant until conditions become favorable again.
I believe that you are referring to a bacterial endospore. Only a small number of bacteria can produce these (Gram-positive Firmicutes). Endospores are very tough and allow the bacteria that can produce them to survive high temperatures, pressures, drought, etc.

Endospores form during a period called binary fission.
