Answer the following question given this paragraph: 

Many organisms form spores for reproduction. Some prokaryotes form spores for survival. Called endospores , they form inside prokaryotic cells when they are under stress. The stress could be UV radiation, high temperatures, or harsh chemicals. Endospores enclose the DNA and help it survive under conditions that may kill the cell. Endospores are commonly found in soil and water. They may survive for long periods of time.
