How they reproduce
Fission: makes two identical cells
Conjugation:when two bacteria attach to each other and combine their genetic material
How the endospore form and what they do
An endospore form when a bacterium forms a thick wall internal TO PROTECT the DNA or the chromosome and then the cell breaks down
What’s decomposition
