Osmosis and Cell Behavior Quiz

Osmosis is defined as the diffusion of water molecules from a region of:

• Low to high water concentration

• High to low water concentration

• High to low salt concentration

• Low to high salt concentration

In a hypotonic solution, such as distilled water, what happens to animal cells?

• They remain unchanged

• They swell and may burst

• They shrink

• They become rigid

What is the role of a contractile vacuole in a paramecium living in freshwater?

• To absorb nutrients

• To store excess salt

• To pump out excess water

• To facilitate energy production

Which of the following statements best describes an isotonic solution?

• Water concentration is higher inside the cell than outside.

• Water concentration is equal on both sides of the membrane.

• Water concentration is lower inside the cell than outside.

• Water concentration varies depending on the type of cell.

In the context of osmosis, what does the term "equilibrium" refer to?

• A state where no water moves across the membrane

• A state where water moves equally in both directions

• A state where cells are actively transporting water

• A state where cells are undergoing plasmolysis

Why might salt on the road negatively affect plants during winter?

• It increases water absorption.

• It causes water to diffuse into the soil.

• It leads to water diffusing out of the plant cells.

• It has no effect on plant cells.

In which direction will water move when a cell is placed in a hypertonic solution?

• Into the cell

• Out of the cell

• No movement occurs

• It depends on the cell type

What does the term "selectively permeable" refer to in the context of the cell membrane?

• It allows all substances to pass freely.

• It only allows certain materials to enter or exit the cell.

• It prevents any substances from entering the cell.

• It allows only water to pass through.

Which of the following processes does NOT require energy from the cell?

• Active transport

• Endocytosis

• Facilitated diffusion

• Protein pump
