Pericycle is an important layer and perform various functions except forming :

Options

A. A part of cambium in dicot stem
B. A part of cork cambium
C. A part of vascular cambium in dicot root
D. Site of origin for lateral roots

Answer

**Step-by-Step Solution:**

1. **Understanding Pericycle:**
- The pericycle is a layer of parenchyma cells located just inside the endodermis of roots. It plays a crucial role in root development and secondary growth.

2. **Functions of Pericycle:**
- The pericycle is known for its ability to form lateral roots. This means that it acts as a site for the initiation of new roots that grow out from the main root.
- It also plays an important role during secondary growth, particularly in dicot roots.

3. **Identifying the Exception:**
- The question asks for a function that is NOT performed by the pericycle.
- One of the options mentioned is "part of cambium in dicot stem."

4. **Analyzing the Options:**
- The pericycle is not involved in forming cambium in the dicot stem, as cambium is primarily found in the vascular tissue of stems and is responsible for secondary growth in stems.
- Therefore, this option is not a function of the pericycle.

5. **Conclusion:**
- Since the question asks for what the pericycle does NOT do, the correct answer is the option related to the "part of cambium in dicot stem."

**Final Answer:**
- The pericycle does not form part of cambium in dicot stem.
