How does a bacteria's structure and reproduction and infection

Structure of bacteria:

Bacteria is a unicellular and prokaryotic organism i. e. made of one cell and no membrane is present around the nucleus. They are found in many shapes such as rods, spherical and cylindrical etc.

Reproduction in bacteria:

In bacteria asexual reproduction occurs such as binary fission. In binary fission, the body of organisms is divided into two equal parts and each part becomes a new organism.
