Understanding Cell Structure and Function

What is the primary function of the nucleus in a eukaryotic cell?

• To produce energy for the cell

• To store the cell's genetic material

• To transport materials within the cell

• To protect the cell from its environment

Which of the following structures is found in both prokaryotic and eukaryotic cells?

• Nucleus

• Plasma membrane

• Mitochondria

• Golgi apparatus

Explain the difference between prokaryotic and eukaryotic cells in terms of their organelles.

• Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.

• Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

• Both prokaryotic and eukaryotic cells have membrane-bound organelles.

• Neither prokaryotic nor eukaryotic cells have membrane-bound organelles.

Identify the part of the cell that is described as the "substance inside a cell, including organelles, but not including the nucleus of a eukaryotic cell."

• Cytoplasm

• Nucleus

• Plasma membrane

• Ribosome

How does the presence of a nucleus in eukaryotic cells affect their complexity compared to prokaryotic cells?

• It makes eukaryotic cells less complex.

• It makes eukaryotic cells more complex.

• It has no effect on the complexity of eukaryotic cells.

• It makes eukaryotic cells simpler.

Which of the following best describes the role of the plasma membrane in a cell?

• It generates energy for the cell.

• It synthesizes proteins for the cell.

• It forms the surface of the cell, separating its contents from the outside world.

• It stores the cell's genetic information.

Compare the structural differences between prokaryotic and eukaryotic cells and discuss how these differences might affect their functions.

• Prokaryotic cells have a nucleus, which allows them to perform more complex functions.

• Eukaryotic cells lack a plasma membrane, which limits their ability to interact with their environment.

• Eukaryotic cells have a nucleus and membrane-bound organelles, which allow for compartmentalization and more complex functions.

• Prokaryotic cells have more organelles, which makes them more efficient in performing cellular functions.

What is the significance of organelles being membrane-bound in eukaryotic cells?

• It allows for the separation of different cellular processes.

• It prevents the cell from interacting with its environment.

• It makes the cell less efficient in performing functions.

• It reduces the complexity of the cell.

Predict how the absence of a nucleus would affect a eukaryotic cell's ability to function.

• The cell would be unable to produce energy.

• The cell would be unable to store genetic information and regulate its activities.

• The cell would be unable to transport materials.

• The cell would be unable to maintain its shape.

Which of the following statements is true regarding the complexity of prokaryotic and eukaryotic cells?

• Prokaryotic cells are more complex due to their lack of a nucleus.

• Eukaryotic cells are more complex due to their membrane-bound organelles and nucleus.

• Both prokaryotic and eukaryotic cells have the same level of complexity.

• Prokaryotic cells are more complex because they have more organelles.
