Let's solve this
Osmosis Worksheet step by step. The goal is to:
1.
Determine the direction of water movement (into or out of the cell) due to osmosis.
2.
Identify the type of solution: isotonic, hypertonic, or hypotonic.

🔍 Key Concepts:
-
Osmosis: Movement of water across a semi-permeable membrane from an area of
lower solute concentration to an area of
higher solute concentration.
-
Isotonic: Equal solute concentration inside and outside the cell →
no net movement of water.
-
Hypertonic: Higher solute concentration
outside the cell → water moves
out of the cell.
-
Hypotonic: Lower solute concentration
outside the cell → water moves
into the cell.
We'll compare the
solute percentage inside the cell vs.
outside the cell.

Let’s go through each diagram:
---
🔹 1.
-
Inside cell: 29% Solute
-
Outside solution: 29% Solute
→
Equal concentrations
✔ No net movement
➡️
Isotonic
>
✔ Circle:
Isotonic
> ➡️ Draw:
No net movement
---
🔹 2.
-
Inside cell: 50% Solute
-
Outside solution: 60% Solute
→ Outside has
more solute, so water moves
out
✔ Water moves
out of the cell
➡️
Hypertonic
>
✔ Circle:
Hypertonic
> ➡️ Draw:
Arrow pointing OUT of the cell
---
🔹 3.
-
Inside cell: 11% Solute
-
Outside solution: 68% Solute
→ Outside has
much more solute, so water moves
out
✔ Water moves
out of the cell
➡️
Hypertonic
>
✔ Circle:
Hypertonic
> ➡️ Draw:
Arrow pointing OUT
---
🔹 4.
-
Inside cell: 75% Solute
-
Outside solution: 75% Solute
→ Equal
✔ No net movement
➡️
Isotonic
>
✔ Circle:
Isotonic
> ➡️ Draw:
No net movement
---
🔹 5.
-
Inside cell: 84% Solute
-
Outside solution: 63% Solute
→ Inside has
more solute, so water moves
in
✔ Water moves
into the cell
➡️
Hypotonic
>
✔ Circle:
Hypotonic
> ➡️ Draw:
Arrow pointing INTO the cell
---
🔹 6.
-
Inside cell: 45% Solute
-
Outside solution: 80% Solute
→ Outside has
more solute, so water moves
out
✔ Water moves
out of the cell
➡️
Hypertonic
>
✔ Circle:
Hypertonic
> ➡️ Draw:
Arrow pointing OUT
---
🔹 7.
-
Inside cell: 59% Solute
-
Outside solution: 42% Solute
→ Inside has
more solute, so water moves
in
✔ Water moves
into the cell
➡️
Hypotonic
>
✔ Circle:
Hypotonic
> ➡️ Draw:
Arrow pointing INTO the cell
---
🔹 8.
-
Inside cell: 10% Solute
-
Outside solution: 10% Solute
→ Equal
✔ No net movement
➡️
Isotonic
>
✔ Circle:
Isotonic
> ➡️ Draw:
No net movement
---
🔹 9.
-
Inside cell: 14% Solute
-
Outside solution: 3% Solute
→ Outside has
less solute, so water moves
in
✔ Water moves
into the cell
➡️
Hypotonic
>
✔ Circle:
Hypotonic
> ➡️ Draw:
Arrow pointing INTO the cell

##
✔ Final Answers Summary:
| # | Water Movement | Solution Type |
|---|------------------------|------------------|
| 1 | No net movement | Isotonic |
| 2 | Out of cell | Hypertonic |
| 3 | Out of cell | Hypertonic |
| 4 | No net movement | Isotonic |
| 5 | Into cell | Hypotonic |
| 6 | Out of cell | Hypertonic |
| 7 | Into cell | Hypotonic |
| 8 | No net movement | Isotonic |
| 9 | Into cell | Hypotonic |

📝 Instructions for Student:
- For each diagram:
- Draw an arrow
into or
out of the cell based on the above.
- Circle the correct term (
Isotonic,
Hypertonic, or
Hypotonic) beside each diagram.
