Question 1

What occurs to a plant cell when it is placed in a hypertonic solution?

Accepted Answer

Plasmolysis

Answer

Turgidity

Answer

Photosynthesis

Answer

Cell division

Question 2

What happens to a plant cell when it is placed in a hypotonic solution?

Accepted Answer

Turgidity

Answer

Cell lysis

Answer

Plasmolysis

Answer

Dehydration

Question 3

What role does turgor pressure play in plant cells?

Accepted Answer

It helps maintain the rigidity and structure of the plant cell.

Answer

It causes the cell to shrink and become plasmolyzed.

Answer

It prevents water from entering the cell.

Answer

It makes the cell wall more flexible.

Question 4

What is the relationship between turgor pressure and wall pressure in plant cells?

Accepted Answer

Turgor pressure pushes against the cell wall, while wall pressure pushes back against the protoplasm.

Answer

Turgor pressure and wall pressure are the same phenomenon.

Answer

Wall pressure eliminates the need for turgor pressure.

Answer

Turgor pressure has no effect on wall pressure.

Question 5

Which factor has the most significant influence on the net water potential of a plant cell?

Accepted Answer

The solute concentration within the cell.

Answer

The size of the leaves on the plant.

Answer

The temperature of the environment.

Answer

The color of the plant's flowers.

Question 6

Why is osmosis considered a passive process?

Accepted Answer

It does not require energy input

Answer

It involves active transport mechanisms

Answer

It occurs only in living cells

Answer

It actively requires ATP

Question 7

What does a semipermeable membrane allow during osmosis?

Accepted Answer

Passage of water while restricting solute movement

Answer

No passage of water or solutes

Answer

Free passage of both water and solutes

Answer

Restriction of water but free passage of solutes

Question 8

What is the primary driving force behind osmosis?

Accepted Answer

Difference in solute concentration

Answer

Temperature variation

Answer

Pressure difference

Answer

Presence of enzymes

Question 9

What drives the passive movement of water into root cells of plants?

Accepted Answer

Answer

Pressure gradient

Answer

Electrical gradient

Answer

Temperature gradient

Question 10
