Question 5

Which structure is found in both prokaryotic and eukaryotic cells and is the site of protein synthesis?

Accepted Answer

Ribosome

Question 6

What is the primary function of lysosomes in animal cells?

Accepted Answer

Digesting excess or worn-out organelles and food particles

Question 7

Which of the following statements correctly compares the cell walls of prokaryotic and plant cells?

Accepted Answer

Cell division

Question 9

Which of the following best explains why mitochondria have a highly folded inner membrane?

Accepted Answer

To increase the surface area for breaking down sugar molecules

Question 10

Which organelle is directly involved in detoxifying harmful substances in liver cells?

Accepted Answer

Smooth endoplasmic reticulum

Question 11

A cell is unable to move proteins to the plasma membrane for secretion. Which organelle is most likely malfunctioning?

Accepted Answer

Golgi apparatus

Question 12

Which of the following is a function of the cytoskeleton?

Accepted Answer

Providing a framework for the cell and enabling movement

Question 13

Which of the following best describes the difference between rough and smooth endoplasmic reticulum?

Temporary storage of water and nutrients

Question 18

Which of the following best explains why animal cells do not have cell walls?

Accepted Answer

Animal cells need to be flexible for movement and interaction with their environment.

Question 19

Which of the following best describes the role of vesicles in eukaryotic cells?

Accepted Answer

They store and transport materials within the cell.

Question 20
