Question

Which statement is NOT true about bacteria?

• A. Their cell wall is made of a slime layer that is the same as in plant cell walls.
• B. Some are photosynthetic.
• C. Some are motile due to flagella.
• D. They are all prokaryotes.

Answer 1

The correct option is A Their cell wall is made of a slime layer that is the same as in plant cell walls.

In bacteria cell wall is made up of peptidoglycan but in plants it is made up of cellulose. The cell wall surrounds the plasma membrane and protects the cell from changes in water pressure.The bacterial cell wall consists of peptidoglycan (or murein), a polymer consisting of NAG and NAM and short chains of amino acids.
