Solved L2 Edit Osmosis Tonicity Worksheet Full Name Section ... - Free Printable

Let's solve this Osmosis/Tonicity Worksheet step by step.

We are given nine beakers, each containing a solution and a cell with its own internal solution. We need to:

1. Draw an arrow showing the direction of water movement (into or out of the cell).
2. Label whether the beaker solution is hypertonic, hypotonic, or isotonic relative to the cell.

🔍 Key Concept: Osmosis & Tonicity

- Water moves from low solute concentration to high solute concentration (via osmosis).
- Tonicity compares the solute concentration outside vs. inside the cell:
- Hypotonic: Beaker has lower solute than cell → Water moves into the cell.
- Hypertonic: Beaker has higher solute than cell → Water moves out of the cell.
- Isotonic: Equal solute concentration → No net movement of water.

We’ll analyze each beaker one by one.

🟦 Beaker 1

- Cell: 90% H₂O, 10% solute
- Beaker: 85% H₂O, 15% solute

→ Beaker has more solute (15%) than cell (10%) → Hypertonic
→ Water moves OUT of the cell
✔ Arrow: ↓ (out)
✔ Label: Hypertonic

---

🟦 Beaker 2

- Cell: 40% H₂O, 60% solute
- Beaker: 90% H₂O, 10% solute

→ Beaker has less solute (10%) than cell (60%) → Hypotonic
→ Water moves INTO the cell
✔ Arrow: ↑ (in)
✔ Label: Hypotonic

---

🟦 Beaker 3

- Cell: 75% H₂O, 25% solute
- Beaker: 80% H₂O, 20% solute

→ Beaker has less solute (20%) than cell (25%) → Hypotonic
→ Water moves INTO the cell
✔ Arrow: ↑ (in)
✔ Label: Hypotonic

---

🟦 Beaker 4

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

→ Beaker has less solute (25%) than cell (55%) → Hypotonic
→ Water moves INTO the cell
✔ Arrow: ↑ (in)
✔ Label: Hypotonic

---

🟦 Beaker 5

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

→ Beaker has more solute (37%) than cell (10%) → Hypertonic
→ Water moves OUT of the cell
✔ Arrow: ↓ (out)
✔ Label: Hypertonic

---

🟦 Beaker 6

- Cell: 50% H₂O, 50% solute
- Beaker: 50% H₂O, 50% solute

→ Equal solute concentrations → Isotonic
→ No net movement
✔ Arrow: ↔ (no movement)
✔ Label: Isotonic

---

🟦 Beaker 7

- Cell: 90% H₂O, 10% solute
- Beaker: 90% H₂O, 10% solute

→ Equal solute concentrations → Isotonic
→ No net movement
✔ Arrow: ↔ (no movement)
✔ Label: Isotonic

---

🟦 Beaker 8

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

→ Beaker has much more solute (75%) than cell (18%) → Hypertonic
→ Water moves OUT of the cell
✔ Arrow: ↓ (out)
✔ Label: Hypertonic

---

🟦 Beaker 9

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

→ Beaker has more solute (20%) than cell (10%) → Hypertonic
→ Water moves OUT of the cell
✔ Arrow: ↓ (out)
✔ Label: Hypertonic

✔ Final Answers Summary:

| Beaker | Water Movement | Tonicity |
|--------|----------------|----------------|
| 1 | Out | Hypertonic |
| 2 | In | Hypotonic |
| 3 | In | Hypotonic |
| 4 | In | Hypotonic |
| 5 | Out | Hypertonic |
| 6 | None | Isotonic |
| 7 | None | Isotonic |
| 8 | Out | Hypertonic |
| 9 | Out | Hypertonic |

---

💡 How to Draw Arrows:

- Use arrow pointing into cell for hypotonic.
- Use arrow pointing out of cell for hypertonic.
- Use double-headed arrow or no arrow for isotonic.
