Let's analyze each beaker one by one based on the concentration of water and solute in the
cell (circle) and the
beaker solution, and determine:
1. Whether the
beaker solution is hypotonic, hypertonic, or isotonic compared to the cell.
2. The
direction of water movement (enter or leave the cell).
---
🔬 Key Concepts:
-
Hypotonic: Lower solute concentration outside than inside → Water
enters the cell.
-
Hypertonic: Higher solute concentration outside than inside → Water
leaves the cell.
-
Isotonic: Equal solute concentration → No net movement of water.
Water moves from areas of
lower solute concentration to areas of
higher solute concentration (osmosis).

🧪 Beaker 1:
-
Cell: 90% H₂O, 10% solute
-
Beaker Solution: 85% H₂O, 15% solute
➡️ Compare solute concentrations:
- Cell: 10% solute
- Beaker: 15% solute →
Higher solute concentration outside
✔ So, the beaker solution is
HYPERTONIC relative to the cell.
➡️ Water will move
from the cell to the beaker →
LEAVE the cell.
---
🧪 Beaker 2:
-
Cell: 40% H₂O, 60% solute
-
Beaker Solution: 90% H₂O, 10% solute
➡️ Compare solute concentrations:
- Cell: 60% solute
- Beaker: 10% solute →
Lower solute concentration outside
✔ So, the beaker solution is
HYPOTONIC relative to the cell.
➡️ Water will move
from the beaker into the cell →
ENTER the cell.
---
🧪 Beaker 3:
-
Cell: 75% H₂O, 25% solute
-
Beaker Solution: 80% H₂O, 20% solute
➡️ Compare solute concentrations:
- Cell: 25% solute
- Beaker: 20% solute →
Lower solute concentration outside
✔ So, the beaker solution is
HYPOTONIC relative to the cell.
➡️ Water will move
from the beaker into the cell →
ENTER the cell.

✔ Final Answers:
| Solution in beaker | Hypertonic | Hypotonic | Hypotonic |
|--------------------|------------|-----------|-----------|
| Movement of water | LEAVE | ENTER | ENTER |
