What is the role of ribosomes in bacterial cells?

• To synthesize lipids

• To generate cellular energy

• To synthesize proteins

• To replicate DNA

What is the nucleoid in a bacterial cell?

Which of the following is a function of the bacterial flagellum?

• To synthesize proteins

• To protect the cell from invaders

• To facilitate cell movement

• To replicate DNA

How do pili differ from flagella in bacterial cells?

• Pili are used for DNA transfer, while flagella are used for movement.

• Pili are used for movement, while flagella are used for DNA transfer.

• Pili are involved in protein synthesis, while flagella are not.

• Pili protect the cell, while flagella are involved in nutrient uptake.

In bacterial cells, where are proteins synthesized?

• In the nucleoid

• On ribosomes

• Within the capsule

• On the cell membrane

What is the primary function of the bacterial cell membrane's phospholipid bilayer?

• To facilitate the movement of proteins within the cell

• To provide structural support to the cell

• To control the passage of substances into and out of the cell

• To store genetic information
