Apical, intercalary and lateral meristems are recognised on the basis of their

Options

A. Specific function
B. Position
C. Mode of formation
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Meristems**: Meristems are specialized tissues in plants that are responsible for growth. They are composed of undifferentiated cells that can divide and differentiate into various types of plant tissues.

2. **Types of Meristems**: There are three main types of meristems:
- **Apical Meristems**: These are located at the tips of roots and shoots. They are responsible for the vertical growth of the plant, helping it to increase in height.
- **Intercalary Meristems**: Found at the base of leaves and at nodes (the regions between leaves), these meristems contribute to the elongation of internodes, allowing the plant to grow taller.
- **Lateral Meristems**: These are located on the lateral sides of stems and roots. They are responsible for the increase in thickness (girth) of the plant, contributing to secondary growth.

3. **Basis of Classification**: The question asks on what basis these meristems are recognized. The correct basis is their **position** within the plant body.
- Apical meristems are at the tips.
- Intercalary meristems are found between nodes and leaves.
- Lateral meristems are located along the sides of stems and roots.

4. **Conclusion**: Therefore, apical, intercalary, and lateral meristems are recognized based on their **position** in the plant body.

**Final Answer**: Apical, intercalary, and lateral meristems are recognized on the basis of their **position**.
