$$6CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 1

Which of the following statements best describes the main difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells contain membrane-bound organelles, including a nucleus, while prokaryotic cells do not.

Question 2

A scientist observes a cell under a microscope and notes the presence of a cell wall, chloroplasts, and a large central vacuole. Which type of cell is being observed?

Accepted Answer

Plant cell

Question 3

Which of the following best explains why the plasma membrane is described as 'selectively permeable'?

Accepted Answer

It allows some substances to pass while restricting others based on size, charge, or solubility.

Question 4

Which process requires energy input from the cell to move substances across the plasma membrane?

Accepted Answer

Active transport

Question 5

A red blood cell is placed in a hypotonic solution. What will most likely happen to the cell, and why?

Accepted Answer

It will swell and possibly burst because water moves in by osmosis.

Question 6

Which organelle is responsible for producing ATP through cellular respiration in both plant and animal cells?

Accepted Answer

Mitochondrion

Question 7

Which of the following best describes the function of the Golgi apparatus?

Accepted Answer

Finishing, sorting, and shipping cell products in vesicles

Question 8

Which of the following equations correctly represents the process of photosynthesis that occurs in chloroplasts?

Accepted Answer

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

Question 9

Which structure is found in animal cells but not in plant cells?

Accepted Answer

Lysosome

Question 10

A mutation prevents the formation of ribosomes in a cell. Which cellular process would be most directly affected?

Accepted Answer

Protein synthesis

Question 11

Which of the following best describes the path of a protein from its synthesis to secretion from a eukaryotic cell?

Accepted Answer

Ribosome → Endoplasmic reticulum → Golgi apparatus → Plasma membrane

Question 12

Which of the following is a function of the large central vacuole in plant cells?

Accepted Answer

Storage of water, nutrients, and waste products

Question 13

Which of the following statements about the nucleus is FALSE?

Accepted Answer

The nucleus is found in all prokaryotic cells.

Question 14

Which of the following best describes the role of the sodium-potassium (Na+/K+) pump in animal cells?

Accepted Answer

It moves sodium and potassium ions against their concentration gradients using ATP.

Question 15

Which of the following is NOT a function of the cytoskeleton in animal cells?

Accepted Answer

Carrying out photosynthesis

Question 16

Which of the following best explains why antibiotics that target bacterial ribosomes do not harm human cells?

Accepted Answer

Bacterial ribosomes are structurally different from eukaryotic ribosomes.

Question 17

Which of the following is a correct statement about osmosis?

Accepted Answer

Osmosis is the movement of water from an area of higher water concentration to an area of lower water concentration.

Question 18

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

Accepted Answer

Plasma membrane

Question 19

A cell is observed to have a rigid outer layer, a large central vacuole, and green structures visible under the microscope. Which process is most likely occurring in these green structures?

Accepted Answer

Photosynthesis

Question 20

Which of the following best describes the flow of genetic information in a eukaryotic cell?

Accepted Answer

$$	ext{DNA} ightarrow 	ext{RNA} ightarrow 	ext{Protein}$$
