In the field of cell biology, understanding the interactions between cells and their surrounding environment is crucial. When a cell is placed in an isotonic solution, it maintains its normal size and shape, as the concentration of solutes inside and outside the cell is equal. This equilibrium results in no net movement of water across the cell membrane.
What Happens to a Cell in an Isotonic Solution
In an isotonic solution, the concentration of solutes is the same on both sides of a cell membrane. This means that water can move freely in and out of the cell, and the cell will neither gain nor lose water.
- Water moves into the cell by osmosis.
- Water moves out of the cell by osmosis.
- The volume of the cell remains the same.
The following table summarizes what happens to a cell in an isotonic solution:
| Characteristic | What Happens |
|---|---|
| Water movement | Water moves freely in and out of the cell. |
| Cell volume | The volume of the cell remains the same. |
| Solute concentration | The concentration of solutes on both sides of the cell membrane is the same. |
Question 1: What is the effect of an isotonic solution on the volume of a cell?
Answer: In an isotonic solution, a cell maintains its normal volume. This is because the concentration of solutes inside the cell is equal to the concentration of solutes outside the cell. As a result, there is no net movement of water across the cell membrane, and the cell’s volume remains constant.
Question 2: What happens to the concentration of a cell when it is placed in an isotonic solution?
Answer: When a cell is placed in an isotonic solution, the concentration of solutes inside the cell remains the same. This is because the cell membrane is selectively permeable, which means that it allows certain substances to pass through while blocking others. As a result, the concentration of solutes outside the cell has no effect on the concentration of solutes inside the cell.
Question 3: Why do cells need to maintain isotonicity?
Answer: Cells need to maintain isotonicity in order to function properly. If a cell is placed in a hypertonic solution, it will lose water and become smaller. This can damage the cell and its ability to function. If a cell is placed in a hypotonic solution, it will gain water and become larger. This can also damage the cell and its ability to function.
