The layers of cells lying between endodermis and vascular bundle is:

Options

A. Cortex
B. Pith
C. Pericycle
D. Exodermis

Answer

To answer the question regarding the layers of cells lying between the endodermis and the vascular bundle, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Layers of Plant Tissues**: Understand the basic structure of roots and stems in flowering plants, which includes various layers such as the epidermis, cortex, endodermis, pericycle, and vascular bundles.

2. **Locate the Endodermis**: The endodermis is a specialized layer of cells that acts as a selective barrier regulating the movement of water and nutrients into the vascular system.

3. **Identify the Vascular Bundle**: Vascular bundles consist of xylem and phloem tissues, which are responsible for the transport of water, minerals, and food throughout the plant.

4. **Determine the Layer Between Endodermis and Vascular Bundle**: The layer of cells that lies between the endodermis and the vascular bundle is known as the pericycle.

5. **Understand the Composition of the Pericycle**: The pericycle is primarily composed of parenchyma and sclerenchyma cells. It is a cylinder of cells that can contribute to the formation of lateral roots.

6. **Conclude the Answer**: Therefore, the correct answer to the question is **pericycle**.

### Final Answer:
The layers of cells lying between the endodermis and vascular bundle is called **pericycle**.
