What are gram stains used for? What are the two types and what do they signify?

What are the steps to binary fission (bacteria’s preferred method of asexual reproduction)?
- A copy is made of the chromosone and the cell elongates
- A septum is formed and begins to split the cell
- The septum is complete and distinct cell walls form.
- The cell seperates into two cells.
What’s conjugation?
Sexual-like reproduction for bacteria.
Cells become linked through pilli. One transfers part of its chromosome to the other, which then undergos binary fission.
Whats endospore?
