TEK 4C: What are endospores and what do they do?

In extreme, harsh environments, some bacteria produce endospores. An endospore is a cell that protects and contains the genetic material of the bacteria in extreme conditions. Bacteria usually produce endospores when they are deprived of nutrients. They can produce endospores after six to eight hours of exposure to harsh conditions. Endospores can survive for thousands of years. Once they are in favorable conditions, the spore can transform into a regular vegetative cell.
