Secondary growth and lateral roots are found in which part of root ?

Options

A. Calyptra region
B. Root hair zone
C. Zone of mature cells
D. Zone of elongation

Answer

To determine where secondary growth and lateral roots are found in the root structure, we can analyze the different regions of a root. Here’s a step-by-step explanation:

### Step-by-Step Solution:

1. **Identify the Regions of the Root**:
- The root is divided into several regions: root cap, meristematic region, elongation region, and maturation region.

2. **Understand Each Region**:
- **Root Cap**: This is the protective tip of the root. It does not participate in secondary growth or lateral root formation.
- **Meristematic Region**: This area is responsible for cell division and growth but does not contribute to secondary growth or lateral roots.
- **Elongation Region**: In this zone, cells elongate, which helps in the growth of the root length. However, secondary growth and lateral roots do not occur here.
- **Maturation Region**: This is where cells differentiate and mature. It is in this region that secondary growth occurs, and lateral roots are formed.

3. **Conclusion**:
- Based on the analysis, secondary growth and lateral roots are found in the **maturation region** of the root.

### Final Answer:
Secondary growth and lateral roots are found in the **maturation region** of the root.
