Question 1

Which of the following is a major structural difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have a nucleus surrounded by a nuclear envelope, while prokaryotic cells do not have a true nucleus.

Question 2

Which organelle is primarily responsible for translating cellular blueprints into proteins?

Accepted Answer

Ribosome

Question 3

What is the main function of the mitochondria in eukaryotic cells?

Accepted Answer

Production of ATP through cellular respiration

Question 4

Which of the following best describes the role of the endomembrane system in eukaryotic cells?

Accepted Answer

It is responsible for the synthesis and transport of lipids and proteins within the cell.

Question 5

If a mutation caused the loss of function in the transport vesicles, which cellular process would be most directly affected?

Accepted Answer

Movement of proteins and lipids between organelles

Question 6

Which equation best represents the process of cellular respiration occurring in mitochondria?

Accepted Answer

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} ightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{energy}$$

Question 7

Which of the following statements about the cell wall in plant cells is correct?

Accepted Answer

The cell wall provides structural support and helps constrain the types of junctions that can be made.

Question 8

Which organelle is responsible for packaging and modifying proteins before they are sent to their final destination?

Accepted Answer

Golgi apparatus

Question 9

Why do mitochondria and chloroplasts have double membranes?

Accepted Answer

Because they are involved in energy conversion processes that require compartmentalization

Question 10

Which of the following is NOT a component of the endomembrane system?

Accepted Answer

Mitochondrion

Question 11

A scientist observes a cell with a nucleus, mitochondria, and a cell wall. Which type of cell is most likely being observed?

Accepted Answer

Plant cell

Question 12

Which of the following best explains why ribosomes are found both free in the cytoplasm and attached to the rough ER?

Accepted Answer

Free ribosomes synthesize proteins for use within the cell, while ER-bound ribosomes synthesize proteins for export or for membranes.

Question 13

Which type of cell junction is most likely to be found in tissues that experience mechanical stress, such as skin?

Accepted Answer

Desmosomes

Question 14

A mutation disrupts the function of lysosomes in a cell. What is the most likely consequence?

Accepted Answer

Cellular waste and damaged organelles will accumulate.

Question 15

Which of the following best describes the function of the cytoskeleton?

Accepted Answer

It provides structural support and facilitates movement within the cell.

Question 16

Which of the following is a function of the smooth endoplasmic reticulum?

Accepted Answer

Lipid synthesis and detoxification

Question 17

Which equation represents the process of photosynthesis occurring in chloroplasts?

Accepted Answer

$$6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{light energy} ightarrow \mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$}$$

Question 18

Which of the following statements is true regarding the plasma membrane?

Accepted Answer

It regulates the movement of substances into and out of the cell.

Question 19

Which organelle contains hydrolytic enzymes for intracellular digestion?

Accepted Answer

Lysosome
