$$ \text{Movement: LOW \rightarrow HIGH} $$

Question 1

Which of the following best describes the function of the cell membrane?

Accepted Answer

It acts as a selectively permeable barrier, controlling what enters and exits the cell.

Question 2

Passive transport across the cell membrane differs from active transport because:

Accepted Answer

Passive transport does not require energy and moves substances down their concentration gradient.

Question 3

Which process is responsible for moving oxygen from the lungs into the blood?

Accepted Answer

Simple diffusion

Question 4

A cell is placed in a hypertonic solution. What will happen to the cell?

Accepted Answer

It will shrink as water leaves the cell.

Question 5

Which organelle is known as the 'powerhouse of the cell' and is responsible for producing ATP?

Accepted Answer

Mitochondria

Question 6

During which phase of mitosis do the chromosomes line up in the center of the cell?

Accepted Answer

Metaphase

Question 7

Which of the following is NOT a function of the Golgi apparatus?

Accepted Answer

Synthesizing proteins

Question 8

Facilitated diffusion differs from simple diffusion because:

Accepted Answer

Facilitated diffusion requires a protein channel to move substances across the membrane.

Question 9

Which equation correctly represents the movement of substances in active transport?

Accepted Answer

$$ 	ext{Movement: LOW ightarrow HIGH} $$

Question 10

Which structure is responsible for synthesizing proteins in the cell?

Accepted Answer

Ribosomes

Question 11

A scientist observes a cell with no nucleus and few organelles. This cell is most likely:

Accepted Answer

A prokaryotic cell

Question 12

Which of the following statements about osmosis is correct?

Accepted Answer

Osmosis is the movement of water across a selectively permeable membrane.

Question 13

Which phase of mitosis is characterized by the splitting of chromosomes and movement to opposite ends of the cell?

Accepted Answer

Anaphase

Question 14

Which of the following is a function of lysosomes?

Accepted Answer

Digesting unwanted bacteria and cellular debris

Question 15

Which of the following is true about facilitated diffusion?

Accepted Answer

It moves large or charged molecules across the cell membrane using protein channels.

Question 16

Which organelle is responsible for synthesizing lipids and detoxifying chemicals in the cell?

Accepted Answer

Smooth endoplasmic reticulum

Question 17

Which of the following best describes the role of ATP in active transport?

Accepted Answer

ATP is required to move substances against their concentration gradient.

Question 18

Which of the following is NOT a type of passive transport?

Accepted Answer

Active transport

Question 19

Which statement about cellular respiration is correct?

Accepted Answer

It occurs in the mitochondria and produces ATP.

Question 20

Which of the following is a correct description of the function of the cytoskeleton?

Accepted Answer

It provides structural support and helps move organelles within the cell.
