Answer:
The structures that some bacteria can create to survive and resist in unfavorable conditions are called spores.
Explanation:
Some types of bacteria, predominantly Gram-positive, develop spores for survival under adverse conditions.
The mechanism by which a bacterium forms spores is called sporulation, and it creates structures capable of withstanding extreme temperatures or pH, lack of water or nutrients, and even radiation.
The three known types of bacterial spores are<u> endospores, exospores and acineto</u>.
- <u><em>Mitotic rings
, endogenous shells or biospheres</em></u><em> are not structures formed by bacteria for their protection.</em>
