Zharick Galeano - Osmosis Worksheet-2 - Osmosis Worksheet name ... - Free Printable

Problem Overview:

The task involves identifying the relative tonicity of solutions and cells in six scenarios and determining the direction of water movement based on osmosis principles. The key terms are:
- Hypotonic: Solution with fewer solutes (more water) than the cell.
- Hypertonic: Solution with more solutes (less water) than the cell.
- Isotonic: Solution with the same concentration of solutes as the cell.

Water moves from an area of low solute concentration (high water concentration) to an area of high solute concentration (low water concentration).

Step-by-Step Solution:

#### Scenario 1:
- Solution: Isotonic
- Cell: Isotonic
- Description: The number of solute particles inside the cell is equal to the number outside the cell.
- Water Movement: Since the concentrations are equal, there is no net movement of water. Water moves equally in and out of the cell.
- Arrow: No net direction (or a bidirectional arrow if indicated).

#### Scenario 2:
- Solution: Hypertonic
- Cell: Hypotonic
- Description: The solution has more solutes than the cell, meaning the cell has more water.
- Water Movement: Water will move out of the cell into the solution to equalize the solute concentrations.
- Arrow: Draw an arrow pointing out of the cell.

#### Scenario 3:
- Solution: Hypotonic
- Cell: Hypertonic
- Description: The solution has fewer solutes than the cell, meaning the solution has more water.
- Water Movement: Water will move into the cell from the solution to equalize the solute concentrations.
- Arrow: Draw an arrow pointing into the cell.

#### Scenario 4:
- Solution: Hypertonic
- Cell: Hypotonic
- Description: The solution has more solutes than the cell, meaning the cell has more water.
- Water Movement: Water will move out of the cell into the solution to equalize the solute concentrations.
- Arrow: Draw an arrow pointing out of the cell.

#### Scenario 5:
- Solution: Hypotonic
- Cell: Hypertonic
- Description: The solution has fewer solutes than the cell, meaning the solution has more water.
- Water Movement: Water will move into the cell from the solution to equalize the solute concentrations.
- Arrow: Draw an arrow pointing into the cell.

#### Scenario 6:
- Solution: Isotonic
- Cell: Isotonic
- Description: The number of solute particles inside the cell is equal to the number outside the cell.
- Water Movement: Since the concentrations are equal, there is no net movement of water. Water moves equally in and out of the cell.
- Arrow: No net direction (or a bidirectional arrow if indicated).

Final Answer:

Summarizing the directions of water movement for each scenario:

1. Isotonic Solution, Isotonic Cell: No net direction (bidirectional).
2. Hypertonic Solution, Hypotonic Cell: Arrow pointing out of the cell.
3. Hypotonic Solution, Hypertonic Cell: Arrow pointing into the cell.
4. Hypertonic Solution, Hypotonic Cell: Arrow pointing out of the cell.
5. Hypotonic Solution, Hypertonic Cell: Arrow pointing into the cell.
6. Isotonic Solution, Isotonic Cell: No net direction (bidirectional).

\boxed{
\begin{array}{c}
\text{1. Bidirectional} \\
\text{2. Out of the cell} \\
\text{3. Into the cell} \\
\text{4. Out of the cell} \\
\text{5. Into the cell} \\
\text{6. Bidirectional}
\end{array}
