Since bacteria are unicellular organisms, when they divide they put them selves at risk. Therefore a bacteria will only divide when the conditions are right from them.

They reproduce via binary fission. Each bacterial cell multiplies into 2, and each other those multiples again into 2.

So: 2 becomes 4, 4 becomes 8, 8 becomes 16 etc…….

They do not need a partner or any exchange of DNA material to reproduce.

This means they reproduce a-sexually.

Much like how our cells divide, bacterial cells must first replicate their DNA and synthesis proteins for cellular replication.
