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

Options

A. Function
B. Position
C. Plane of division
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Meristems**: Begin by defining what meristems are. Meristems are regions in plants that contain undifferentiated cells capable of division and growth. They are responsible for the growth of the plant.

2. **Types of Meristems**: Identify the three main types of meristems:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for the elongation of these structures.
- **Intercalary Meristem**: Found at the nodes or internodes of stems, aiding in the elongation of the stem.
- **Lateral Meristem**: Located along the sides of stems and roots (e.g., vascular cambium and cork cambium), responsible for increasing the girth of the plant.

3. **Basis of Recognition**: Analyze how these meristems are recognized:
- **Position**: Each type of meristem is found in a specific location within the plant (apical at tips, intercalary at internodes, and lateral along the sides).
- **Function**: While they have specific functions (elongation, growth), the question focuses on how they are categorized.
- **Plane of Division**: This refers to how cells divide but is not the primary basis for distinguishing these meristems.

4. **Conclusion**: Based on the above analysis, apical, intercalary, and lateral meristems are recognized primarily on the basis of their position within the plant.

5. **Final Answer**: The correct answer is that apical, intercalary, and lateral meristems are recognized on the basis of their **position**.
