The apical meristem of shoot apex is

Options

A. intercalary meristem
B. primary meristem
C. secondary meristem
D. laterl meristem

Answer

**Step-by-Step Solution:**

1. **Identify the Types of Meristems**:
- Understand that meristems are categorized into different types based on their location and function. The main types include apical meristem, intercalary meristem, lateral meristem, primary meristem, and secondary meristem.

2. **Define Apical Meristem**:
- Apical meristem is located at the tips of roots and shoots. Its primary function is to facilitate the vertical growth of the plant, contributing to an increase in height.

3. **Differentiate Between Meristem Types**:
- Intercalary meristem is found at the nodes and helps in cell division and elongation.
- Lateral meristem is responsible for secondary growth, which increases the girth of the plant.
- Primary meristems include apical and intercalary meristems, which are involved in the early growth stages of the plant.

4. **Determine the Nature of the Apical Meristem**:
- Since the apical meristem is involved in the primary growth of the plant and appears during its early life, it is classified as a primary meristem.

5. **Conclusion**:
- Based on the definitions and functions of the different types of meristems, the apical meristem of the shoot apex is identified as a primary meristem.

**Final Answer**: The apical meristem of the shoot apex is a primary meristem.
