Select an incorrect statement regarding meristematic tissue

Options

A. All the cells of the embryo of a plant are capable of division
B. A meristem is a localised region in which actual cell division occurs
C. According to their origin and development, meristems are classified as promeristem, primary meristem and secondary meristem.
D. The meristem may also be classified according to their function in the plant body as apical, intercalary and lateral

Explanation

To solve the question of selecting an incorrect statement regarding meristematic tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Meristematic Tissue**:
- Meristematic tissue is a type of plant tissue that is responsible for growth. It consists of actively dividing cells that can differentiate into various types of cells.

2. **Identify Types of Meristematic Tissue**:
- Meristematic tissue can be classified based on position into:
- **Apical Meristem**: Located at the tips of roots and stems.
- **Lateral Meristem**: Found along the sides of stems and roots, responsible for secondary growth.
- **Intercalary Meristem**: Found at the nodes and base of leaves, allowing for growth in length.

3. **Classification Based on Origin and Development**:
- Meristematic tissue can also be classified based on origin and development into:
- **Pro Meristem**: The initial meristematic tissue.
- **Primary Meristem**: Derived from the pro meristem and gives rise to primary tissues.
- **Secondary Meristem**: Responsible for secondary growth.

4. **Evaluate the Statements**:
- **Statement 1**: "Cells of the embryo of the plant are capable of division."
- This statement is correct as embryonic cells are meristematic.
- **Statement 2**: "Meristem is a localized region in which actual cell division occurs."
- This statement is also correct as it describes the function of meristematic tissue.
- **Statement 3**: "According to their origin and development, meristems are classified as pro-meristem, primary-meristem, and secondary-meristem."
- This statement is correct as it accurately describes the classification based on origin and development.
- **Statement 4**: "The meristem may also be classified according to their function in the plant body as apical, endocannular and lateral."
- This statement is incorrect because the classification of meristematic tissue is based on position (apical, lateral, intercalary) and not function. The term "endocannular" is not a recognized classification.

5. **Conclusion**:
- The incorrect statement regarding meristematic tissue is **Statement 4**.

### Final Answer:
The incorrect statement regarding meristematic tissue is: **"The meristem may also be classified according to their function in the plant body as apical, endocannular and lateral."**
