• Protect the cell

• Control cell division

What is the shape of the chromosome in prokaryotic cells?

• Linear

• Spiral

• Circular

• Helical

What is the role of the plasma membrane in a cell?

• Produces energy

• Controls what enters and leaves the cell

• Stores genetic information

• Synthesizes proteins

What is a defining feature of eukaryotic cells?

• They lack a nucleus.

• They have a nucleus and membrane-bound organelles.

• They have a cell wall only.

• They do not have any organelles.

What is the function of the cell wall in eukaryotic cells?

• It synthesizes proteins.

• It is a strong barrier outside the cell membrane.

• It contains the cell's DNA.

• It makes ribosomes.

What is the primary role of the nucleus in a cell?

• It makes proteins.

• It contains most of the cell's DNA.

• It synthesizes lipids.

• It supports and suspends organelles.
