Osmosis Worksheet: Animal cells in beakers with different solute concentrations, demonstrating water movement via osmosis.

Looking at the third row of diagrams:

For the first pair:
- Cell: 90% H₂O, 10% solute (the top part is cut off but shows "10% solute")
- Beaker: 90% H₂O, 10% solute
Water will not move (equal concentrations). The beaker solution is isotonic relative to the cell.

For the second pair:
- Cell: 82% H₂O, 18% solute
- Beaker: 25% H₂O, 75% solute
Water will move from the cell (higher water concentration) to the beaker (lower water concentration). The beaker solution is hypertonic relative to the cell.

For the third pair:
- Cell: 90% H₂O, 10% solute
- Beaker: 80% H₂O, 20% solute
Water will move from the cell (higher water concentration) to the beaker (lower water concentration). The beaker solution is hypertonic relative to the cell.

I've now analyzed all the diagrams. Let me summarize the complete solution for each pair.

Solution Summary:

Row 1:
1. Cell (90% H₂O) → Beaker (85% H₂O): Water moves OUT of cell. Beaker is HYPERTONIC.
2. Cell (40% H₂O) ← Beaker (90% H₂O): Water moves INTO cell. Beaker is HYPOTONIC.
3. Cell (75% H₂O) ← Beaker (80% H₂O): Water moves INTO cell. Beaker is HYPOTONIC.

Row 2:
1. Cell (45% H₂O) ← Beaker (75% H₂O): Water moves INTO cell. Beaker is HYPOTONIC.
2. Cell (90% H₂O) → Beaker (63% H₂O): Water moves OUT of cell. Beaker is HYPERTONIC.
3. Cell (50% H₂O) ↔ Beaker (50% H₂O): No water movement. Beaker is ISOTONIC.

Row 3:
1. Cell (90% H₂O) ↔ Beaker (90% H₂O): No water movement. Beaker is ISOTONIC.
2. Cell (82% H₂O) → Beaker (25% H₂O): Water moves OUT of cell. Beaker is HYPERTONIC.
3. Cell (90% H₂O) → Beaker (80% H₂O): Water moves OUT of cell. Beaker is HYPERTONIC.

All percentages are already filled in on the worksheet, so no missing values need to be calculated. The arrows should be drawn according to the water movement directions I've identified, and each solution type should be labeled as specified.
