Understanding Osmosis and Osmolarity

What is the primary characteristic of osmosis?

• It requires energy from the cell.

• It occurs only in plant cells.

• It involves the movement of solutes.

• It is a passive process.

How does water move during osmosis?

• From low solute concentration to high solute concentration.

• From high water concentration to low water concentration.

• From low water concentration to high water concentration.

• From high solute concentration to low solute concentration.

What is a solute?

• A substance that cannot dissolve.

• A gas that evaporates in air.

• A solid that has been dissolved in a liquid.

• A liquid that dissolves in water.

What does osmolarity measure?

• The energy required for osmosis.

• The speed of water movement.

• The total solute concentration per liter of solution.

• The amount of water in a solution.

What happens when a fluid has high osmolarity?

• It has equal amounts of solutes and water.

• It has more solutes and less water.

• It has fewer solutes and more water.

• It has more water and fewer solutes.
