Osmosis and Solution Types

The video tutorial covers an osmosis worksheet, focusing on three main tasks: drawing arrows to show water movement, filling in missing percentages of water and solute, and identifying solution types as isotonic, hypertonic, or hypotonic. The teacher provides examples and explanations for each task, emphasizing the importance of understanding water movement and solution types. Students are encouraged to complete the worksheet independently, using the provided guidelines and examples.

What is the first task you need to complete on the osmosis worksheet?

• Fill in missing percentages

• Calculate the solute concentration

• Draw an arrow to show water movement

• Identify the type of solution

Which type of solution causes a cell to shrink due to water loss?

• Isotonic

• Hypotonic

• Hypertonic

• Neutral

In a hypertonic solution, where does the water move?

• Equally in and out of the cell

• Out of the cell

• Into the cell

• It does not move

If a cell has 90% water and 10% solute, and the surrounding solution has 85% water, what type of solution is it?

• Hypertonic

• Hypotonic

• Neutral

• Isotonic

What happens to a cell in a hypotonic solution?

• It shrinks

• It stays the same

• It swells and may burst

• It becomes rigid

In an isotonic solution, how does water move across the cell membrane?

• It does not move

• Freely in both directions with no net change

• Only out of the cell

• Only into the cell

Which solution type has equal water movement in and out of the cell?

• Hypertonic

• Hypotonic

• Neutral

• Isotonic

If a solution outside the cell has 80% water and 20% solute, what is the solute percentage inside the cell if it has 85% water?

• 25%

• 10%

• 15%

• 20%

What is the final step in completing the osmosis worksheet?

• Identifying solution types

• Drawing arrows for water movement

• Calculating the total solute

• Filling in missing percentages

What should you remember about the percentages of water and solute in a solution?

• They should be different

• They should add up to 50%

• They should add up to 100%

• They should be equal
