Osmosis Video

What is the primary reason that applying salt to icy roads can harm nearby plants?

• The salt makes the soil too acidic for plant growth.

• The salt lowers the freezing point of water, causing plants to freeze.

• The salt increases the solute concentration in the soil, drawing water out of plant cells.

• The salt directly poisons the plant cells, leading to their death.

Which statement accurately describes the movement of water during osmosis?

• Water moves from an area of low water concentration to an area of high water concentration.

• Water moves from an area of high solute concentration to an area of low solute concentration.

• Water moves from an area of high water concentration to an area of low water concentration.

• Water moves against its concentration gradient, requiring energy.

In the U-tube experiment, if Side A contains pure water and Side B contains water with a high concentration of salt, which term best describes Side B relative to Side A?

• Hypotonic

• Isotonic

• Hypertonic

• Osmotic

What would happen to the red blood cells if a patient were given an intravenous (IV) solution of pure water instead of an isotonic solution?

• The red blood cells would shrink due to water leaving the cells.

• The red blood cells would remain stable, as pure water is harmless.

• The red blood cells would swell and potentially burst due to water entering the cells.

• The red blood cells would become hypertonic, causing them to become more efficient.
