Lateral roots arise from

Options

A. cortex
B. Endodermis
C. Cork cambium
D. Pericycle

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question:**
The question asks where lateral roots arise from in flowering plants.

2. **Identifying the Options:**
The options provided are:
- Cortex
- Endodermis
- Caulicium
- Pericycle

3. **Analyzing the Options:**
- **Cortex:** This is the outer layer of the root, primarily involved in storage and transport but does not give rise to lateral roots.
- **Endodermis:** This is the innermost layer of the cortex, which regulates the flow of water and nutrients, but it is not the origin of lateral roots.
- **Caulicium:** This term seems to be a typographical error or confusion with "cambium," which is involved in secondary growth but does not produce lateral roots.
- **Pericycle:** This is a layer of cells located just inside the endodermis and is responsible for the formation of lateral roots.

4. **Conclusion:**
Based on the analysis, lateral roots arise from the pericycle. This layer is crucial as it contains cells that can divide and form new roots, contributing to the plant's overall root system.

5. **Final Answer:**
Lateral roots arise from the pericycle.
