Osmosis Worksheet: Students analyze animal cells in beakers with different water and solute concentrations, determining water movement, completing percentages, and identifying solution types.

I'll solve this osmosis worksheet by analyzing each of the 9 beaker scenarios. I need to determine the direction of water movement, fill in any missing percentages, and identify the type of solution (isotonic, hypertonic, or hypotonic).

Let me start by examining each beaker systematically.

First, I'll look at the top-left beaker:
- Cell: 90% H₂O, 10% solute
- Beaker: 85% H₂O, 15% solute

Since the cell has a higher concentration of water (90%) than the beaker (85%), water will move from the cell to the beaker (out of the cell). This is a hypertonic solution for the cell (higher solute concentration outside).

Now, let me examine the top-middle beaker:
- Cell: 40% H₂O, 60% solute
- Beaker: 90% H₂O, 10% solute

The beaker has a much higher water concentration (90%) than the cell (40%), so water will move into the cell. This is a hypotonic solution for the cell (lower solute concentration outside).

For the top-right beaker:
- Cell: 75% H₂O, 25% solute
- Beaker: 80% H₂O, 20% solute

The beaker has a higher water concentration (80%) than the cell (75%), so water will move into the cell. This is a hypotonic solution for the cell.

Let me continue with the middle row:

Middle-left beaker:
- Cell: 45% H₂O, 55% solute
- Beaker: 75% H₂O, 25% solute

The beaker has a higher water concentration (75%) than the cell (45%), so water will move into the cell. This is a hypotonic solution for the cell.

Middle-center beaker:
- Cell: 90% H₂O, 10% solute
- Beaker: 63% H₂O, 37% solute

The cell has a higher water concentration (90%) than the beaker (63%), so water will move out of the cell. This is a hypertonic solution for the cell.

Middle-right beaker:
- Cell: 50% H₂O, 50% solute
- Beaker: 50% H₂O, 50% solute

The concentrations are equal, so there will be no net movement of water. This is an isotonic solution.

Now for the bottom row:

Bottom-left beaker:
- Cell: 90% H₂O, 10% solute
- Beaker: 90% H₂O, 10% solute

The concentrations are equal, so there will be no net movement of water. This is an isotonic solution.

Bottom-middle beaker:
- Cell: 82% H₂O, 18% solute
- Beaker: 25% H₂O, 75% solute

The cell has a higher water concentration (82%) than the beaker (25%), so water will move out of the cell. This is a hypertonic solution for the cell.

Bottom-right beaker:
- Cell: 90% H₂O, 10% solute
- Beaker: 80% H₂O, 20% solute

The cell has a higher water concentration (90%) than the beaker (80%), so water will move out of the cell. This is a hypertonic solution for the cell.

All percentages are complete in the image, so no missing values need to be filled in.

Here's the complete solution for each beaker:

1. Top-left: Water moves OUT of cell; Hypertonic solution
2. Top-middle: Water moves INTO cell; Hypotonic solution
3. Top-right: Water moves INTO cell; Hypotonic solution
4. Middle-left: Water moves INTO cell; Hypotonic solution
5. Middle-center: Water moves OUT of cell; Hypertonic solution
6. Middle-right: No net water movement; Isotonic solution
7. Bottom-left: No net water movement; Isotonic solution
8. Bottom-middle: Water moves OUT of cell; Hypertonic solution
9. Bottom-right: Water moves OUT of cell; Hypertonic solution
