In a dicot root, the pericycle gives rise to

Options

A. Lateral roots
B. Cork cambium
C. A portion of vascular cambium
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understand the Structure of a Dicot Root:**
- A dicot root consists of several layers, including the epidermis, cortex, endodermis, pericycle, and vascular bundles (xylem and phloem).
- The pericycle is a layer of parenchymatous tissue located just inside the endodermis.

2. **Identify the Role of the Pericycle:**
- The pericycle is significant in the formation of lateral roots. It is the layer from which lateral roots emerge.
- In addition to lateral roots, the pericycle also gives rise to the cambium, which is important for secondary growth.

3. **Evaluate the Options:**
- **Option A: Lateral Roots** - Correct, as the pericycle is responsible for the formation of lateral roots.
- **Option B: Cork Cambium** - Correct, as the pericycle can give rise to the cork cambium in roots.
- **Option C: A Portion of Vascular Cambium** - Correct, as some vascular cambium can also develop from the pericycle.
- **Option D: All of the Above** - Since all previous options are correct, this option is also correct.

4. **Conclusion:**
- The pericycle in a dicot root gives rise to lateral roots, cork cambium, and a portion of vascular cambium. Therefore, the correct answer is **Option D: All of the Above**.
