Intercalary meristem is located in:

Options

A. petiole and internode
B. stem tip
C. root
D. bud

Answer

**Step-by-Step Solution:**

1. **Understanding Meristem**: Begin by defining what meristematic tissue is. Meristem is a type of plant tissue that is responsible for growth. It consists of undifferentiated cells that can divide and differentiate into various types of plant cells.

2. **Identifying Types of Meristem**: There are different types of meristematic tissues in plants, including apical meristem, lateral meristem, and intercalary meristem. Each type is located in specific parts of the plant.

3. **Evaluating the Options**:
- **Option 1: Petiole and Internode**: This option suggests that intercalary meristem is located in the petiole (the stalk that attaches the leaf to the stem) and internodes (the segments between nodes on a stem).
- **Option 2: Stem Tip**: The stem tip contains shoot apical meristem, which is responsible for the growth of the stem and leaves. This is not where intercalary meristem is found.
- **Option 3: Root**: Roots contain root apical meristem, which is involved in root growth. Intercalary meristem is not located here.
- **Option 4: Bud**: Buds do not contain intercalary meristem; they contain meristematic tissue that is specific to bud development.

4. **Conclusion**: After evaluating all the options, the only correct answer is **Option 1: Petiole and Internode**, where intercalary meristem is indeed located. This type of meristem allows for the elongation of nodes and internodes, contributing to the growth of the plant.

**Final Answer**: Intercalary meristem is located in the petiole and internode.
