A single large central vacuole occurs in

Options

A. Mature animal cell
B. Mature plant cell
C. Developing animal cells
D. Developing plant cells

Answer

To answer the question "A single large central vacuole occurs in," we will analyze the options provided and determine which type of cell typically contains a large central vacuole.

### Step-by-Step Solution:

1. **Understanding Vacuoles**:
- Vacuoles are membrane-bound organelles found in cells. They are primarily involved in storage and maintaining the cell's internal environment.

2. **Identifying Cell Types**:
- We need to consider the types of cells mentioned in the options:
a. Mature animal cells
b. Mature plant cells
c. Developing animal cells
d. Developing plant cells

3. **Characteristics of Vacuoles**:
- In plant cells, vacuoles can be quite large and serve multiple functions, including storage of nutrients, waste products, and helping maintain turgor pressure (the pressure of the cell contents against the cell wall).

4. **Analyzing Each Option**:
- **Mature Animal Cells**: Typically have small vacuoles, not a single large central vacuole.
- **Mature Plant Cells**: Characteristically contain a single large central vacuole that occupies a significant portion of the cell's volume.
- **Developing Animal Cells**: May have small vacuoles but not a large central one.
- **Developing Plant Cells**: May have vacuoles, but they are not as prominent as in mature plant cells.

5. **Conclusion**:
- Based on the analysis, the option that correctly identifies where a single large central vacuole occurs is **b. mature plant cell**.

### Final Answer:
**The correct answer is b. mature plant cell.**
