Which membrane is responsible for setting up higher concentration of ions in the vacuole as compared to cytoplasm.

Answer

**Step-by-Step Solution:**

1. **Identify the Structure**: The question asks about a membrane that creates a higher concentration of ions in the vacuole compared to the cytoplasm.

2. **Understand the Function of Vacuoles**: Vacuoles are membrane-bound organelles found in both plant and animal cells. Their primary function is to store excess or unwanted materials.

3. **Recognize the Membrane**: The membrane that separates the vacuole from the cytoplasm is crucial for maintaining different concentrations of ions.

4. **Name the Membrane**: This specific membrane is known as the **tonoplast**.

5. **Explain the Role of the Tonoplast**: The tonoplast is responsible for regulating the movement of ions and other substances into and out of the vacuole, thus creating a higher concentration of ions within the vacuole compared to the cytoplasm.

6. **Conclude**: Therefore, the membrane responsible for setting up a higher concentration of ions in the vacuole as compared to the cytoplasm is the **tonoplast**.

**Final Answer**: The membrane responsible for setting up a higher concentration of ions in the vacuole compared to the cytoplasm is the **tonoplast**.
