The layer of cells outside the phloem meant for giving rise to the root branches is called

Options

A. Combium
B. Corpus
C. Endodermis
D. Percycle

Answer

To solve the question about the layer of cells outside the phloem that gives rise to root branches, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Roots**:
- Roots have several layers, and it's important to know their arrangement from the outermost to the innermost.

2. **Identify the Layers**:
- The outermost layer is the **epidermis**.
- Below the epidermis is the **hypodermis**.
- Following the hypodermis is the **cortex**.
- Next is the **endodermis**.
- After the endodermis, we find the **pericycle**.
- Finally, the innermost layer is the **pith** (or medulla), where the vascular bundles, including phloem, are located.

3. **Locate the Phloem**:
- The phloem is responsible for the transportation of food materials in plants and is situated towards the inner part of the root structure.

4. **Identify the Layer Outside the Phloem**:
- The layer of cells that is immediately outside the phloem is the **pericycle**.

5. **Understand the Function of the Pericycle**:
- The pericycle is significant because it is responsible for giving rise to lateral roots. This means that it plays a crucial role in root branching.

6. **Select the Correct Answer**:
- Based on the identification and understanding of the layers, the correct answer to the question is **pericycle**.

### Final Answer:
The layer of cells outside the phloem meant for giving rise to the root branches is called the **pericycle**.
