Casparian strip is a characteristic feature of

Options

A. Pericycle
B. Periblem
C. Endodermis
D. Hypodermis

Answer

**Step-by-Step Solution:**

1. **Understanding the Casparian Strip**: The Casparian strip is a specialized structure found in plant roots. It is composed of a band of suberin, a waxy substance that helps regulate the flow of water and nutrients.

2. **Identifying the Location**: The Casparian strip is specifically located in the endodermis, which is the innermost layer of the cortex in plant roots.

3. **Characteristics of the Endodermis**: The endodermis is characterized by the presence of the Casparian strip, which appears as ribbon-like lignified bands. These bands are found on the radial and tangential walls of the endodermal cells.

4. **Examining the Options**: The question provides four options: pericycle, periblem, endodermis, and hypodermis.
- **Pericycle**: This is the layer just inside the endodermis, but it does not contain the Casparian strip.
- **Periblem**: This refers to the outer layer of the meristematic tissue, which is not related to the Casparian strip.
- **Hypodermis**: This is the layer beneath the epidermis, also not related to the Casparian strip.

5. **Conclusion**: Since the Casparian strip is a defining feature of the endodermis, the correct answer to the question is **endodermis**.

**Final Answer**: The Casparian strip is a characteristic feature of the **endodermis**.
