Wood is separated from phloem in dicots by

Options

A. Pericycle
B. Cortex
C. Vascular cambium
D. Interfascicular cambium

Answer

To solve the question "Wood is separated from phloem in dicots by," we need to analyze the options provided and understand the structure of dicot stems.

### Step-by-Step Solution:

1. **Understanding the Structure of Dicot Stems**:
- In dicots, the vascular system consists of xylem (wood) and phloem (the tissue responsible for transporting nutrients).
- Between the xylem and phloem, there is a layer of tissue that plays a crucial role in the growth of the plant.

2. **Identifying the Options**:
- The options given are:
a) Pericycle
b) Cortex
c) Vascular cambium
d) Interfascicular cambium

3. **Analyzing Each Option**:
- **Pericycle**: This is a layer of cells located just inside the endodermis in roots and does not separate xylem from phloem in stems. Thus, this option is incorrect.
- **Cortex**: This is the outer layer of the stem and root, primarily made up of ground tissue. It does not separate xylem from phloem, making this option incorrect as well.
- **Vascular Cambium**: This is a layer of meristematic tissue that is responsible for the secondary growth in plants. It is located between the xylem and phloem and is responsible for the production of new xylem and phloem cells. Therefore, this option is correct.
- **Interfascicular Cambium**: This type of cambium develops from the medullary rays and is found between vascular bundles. However, it does not directly separate xylem from phloem, making this option incorrect.

4. **Conclusion**:
- The correct answer is **Vascular Cambium**, as it is the tissue that separates wood (xylem) from phloem in dicots.

### Final Answer:
Wood is separated from phloem in dicots by **Vascular Cambium**.
