Growth in plants is largely restricted to specialized regions of active cell division called

Options

A. Meristems
B. Cambium
C. Primordium
D. Permanent tissue

Explanation

**Step-by-Step Solution:**

1. **Understanding Plant Growth**: Growth in plants occurs in specific areas where cells actively divide. This is different from other tissues in the plant that may not divide as frequently.

2. **Identifying Active Cell Division Regions**: The regions where this active cell division takes place are known as meristems. These are specialized tissues that are responsible for the growth of the plant.

3. **Types of Meristems**: There are different types of meristems, including:
- **Apical Meristems**: Located at the tips of roots and shoots, responsible for primary growth (lengthening).
- **Lateral Meristems**: Such as the cambium, responsible for secondary growth (thickening).
- **Intercalary Meristems**: Found at the base of leaves or internodes, contributing to growth in certain plants.

4. **Choosing the Correct Answer**: Given the options provided (Meristems, Cambium, Primodium, Permanent Tissue), the term that best describes the regions of active cell division in plants is "Meristems".

5. **Conclusion**: Therefore, the correct answer to the question is "Meristems".

**Final Answer**: Option 1, Meristems.
