The meristerms that develop during later stages of plant growth

Options

A. Promeristems
B. Primay meristems
C. Secondary meristems
D. Both (1) and (3)

Answer

### Step-by-Step Solution:

1. **Understanding Meristems**: Begin by defining what meristems are. Meristems are regions in plants where cells remain undifferentiated and are capable of division, leading to growth.

2. **Types of Meristems**: There are two main types of meristems:
- **Primary Meristems**: These are responsible for the primary growth of plants, which includes the elongation of roots and shoots. They arise from the promeristem and are present at the tips of roots and shoots.
- **Secondary Meristems**: These are responsible for secondary growth, which increases the thickness of stems and roots. They develop later in the plant's life cycle.

3. **Identifying the Correct Answer**: The question specifically asks about meristems that develop during the later stages of plant growth. Since primary meristems are involved in initial growth and are present from the beginning, they do not fit the criteria. Therefore, the correct answer is secondary meristems.

4. **Conclusion**: The meristems that develop during the later stages of plant growth are the secondary meristems.

### Final Answer:
The meristems that develop during later stages of plant growth are **secondary meristems**.
