What is the function of the cell wall in a bacterial cell?

Regulates the movement of substances in and out of the cell

Contains enzymes and other molecules involved in metabolic processes

Forms communities of bacteria that adhere to surfaces

Provides structural support and protection to the cell (correct)

Where is the genetic material in bacteria present?

In the biofilms as communities of bacteria that adhere to surfaces

In the cell wall as small circular pieces of DNA called plasmids

In the flagella as long, whip-like structures that rotate to propel the cell

In the cytoplasm in the form of a single circular chromosome (correct)
