Choose the correct statement regarding pericycle in dicot root.

Options

A. It is parenchymatous.
B. It gives rise to cork cambium.
C. Casparing bands and passage cells
D. Passage cells and starch

Answer

To answer the question regarding the pericycle in dicot roots, let's analyze the statements provided and determine which one is correct.

### Step-by-Step Solution:

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

2. **Analyzing the Options**:
- **Option 1**: "The pericycle is parenchymatous at young and sclerenchymatous at maturity."
- This statement is incorrect. The pericycle is primarily parenchymatous and does not typically become sclerenchymatous.

- **Option 2**: "The pericycle gives rise to cambium."
- This statement is also incorrect. While the pericycle can give rise to cork cambium, it does not give rise to the vascular cambium.

- **Option 3**: "Casparian bands are present in dicot roots."
- This statement is incorrect. Casparian bands are characteristic of the endodermis and are found in monocots, not dicots.

- **Option 4**: "Passage cells and starch are formed by the pericycle."
- This statement is correct. The pericycle can give rise to passage cells and is involved in the storage of starch.

3. **Conclusion**:
- The correct statement regarding the pericycle in dicot roots is **Option 4**: "Passage cells and starch are formed by the pericycle."
