Casparian strips of endodermis has deposition of

Options

A. Waxy materials
B. Lignin or pectin
C. Suberin
D. Chitin

Answer

**Step-by-Step Solution:**

1. **Understanding Casparian Strips**: The Casparian strips are specialized structures found in the endodermis of plant roots. They play a crucial role in regulating the movement of water and solutes into the vascular system of the plant.

2. **Composition of Casparian Strips**: The Casparian strips are primarily composed of a substance that is hydrophobic, meaning it repels water. This characteristic is essential for their function in controlling water movement.

3. **Identifying the Substance**: The specific substance that makes up the Casparian strips is known as suberin. Suberin is a waxy substance that forms a barrier, preventing water and dissolved substances from passing freely through the endodermis.

4. **Function of Casparian Strips**: The main function of the Casparian strips is to ensure that water and nutrients absorbed by the roots are directed into the vascular tissues of the plant, rather than leaking back into the soil.

5. **Conclusion**: Therefore, the Casparian strips of the endodermis have a deposition of suberin.

**Final Answer**: The Casparian strips of endodermis have deposition of **suberin**.
