Among the following, one is not the function of growth inhibitor

Options

A. Flowering and seed dormancy
B. Seed formation and abscission
C. Dormancy of seeds and abscission
D. Cell division and flowering

Answer

### Step-by-Step Text Solution:

1. **Understanding Growth Inhibitors**: Growth inhibitors are substances that slow down or inhibit the growth and developmental processes in plants. They play a crucial role in regulating various physiological processes.

2. **Identifying Functions of Growth Inhibitors**: Common functions of growth inhibitors include:
- **Retarding Cell Elongation**: They prevent the elongation of plant cells.
- **Inducing Abscission**: They promote the dropping of leaves, fruits, and flowers.
- **Inducing Senescence**: They cause aging in plant parts.
- **Creating Dormancy**: They induce a state where seeds or buds remain inactive.

3. **Analyzing the Options**: The question provides four options, and we need to identify which one is not a function of growth inhibitors:
- **Option 1**: Flowering and seed dormancy
- **Option 2**: Seed formation and abscission
- **Option 3**: Dormancy of seeds and abscission
- **Option 4**: Cell division

4. **Evaluating Each Option**:
- **Option 1**: Flowering is promoted by ethylene, while seed dormancy can be induced by abscisic acid (ABA). Since flowering is not a function of growth inhibitors, this option is a candidate.
- **Option 2**: Seed formation is not a function of growth inhibitors, but abscission is. This option is also a candidate.
- **Option 3**: Both dormancy of seeds and abscission are functions of growth inhibitors. This option is not correct.
- **Option 4**: Cell division is a growth process. Growth inhibitors actually inhibit cell division, making this option a strong candidate for the answer.

5. **Conclusion**: The option that is not a function of growth inhibitors is **Option 4: Cell division**. This is because growth inhibitors are meant to slow down or stop growth, including cell division.

### Final Answer:
**Cell division** is not a function of growth inhibitors.
