The parts removed by herbivorous animals are regenerated by

Options

A. Apical meristems
B. Lateral meristems
C. Intercalary meristems
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the regeneration of parts removed by herbivorous animals from plants. This implies that we need to identify which type of meristematic tissue is responsible for this regeneration.

2. **Identifying the Types of Meristematic Tissues**: There are three main types of meristematic tissues in plants:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for the vertical growth of the plant.
- **Lateral Meristem**: Found in the vascular and cork cambium, responsible for the increase in girth (diameter) of the plant.
- **Intercalary Meristem**: Located at the base of leaves or internodes, responsible for the growth of the plant in length and also plays a crucial role in regeneration.

3. **Analyzing the Options**:
- **Apical Meristem**: This type of meristem is not responsible for regeneration of parts that have been removed; it primarily aids in the growth of the plant's height.
- **Lateral Meristem**: This contributes to the thickening of the plant but does not specifically regenerate lost parts.
- **Intercalary Meristem**: This is the key player in the regeneration of parts that have been removed, as it is located at the nodes and helps in regrowth after herbivores have grazed on the plant.
- **All**: Since not all types of meristematic tissues are involved in regeneration, this option is incorrect.

4. **Conclusion**: The correct answer is **Intercalary Meristem**, as it specifically aids in the regeneration of parts removed by herbivorous animals.

**Final Answer**: The parts removed by herbivorous animals are regenerated by **Intercalary Meristem**.
