Water impermeable, waxy material suberin in the form of strips is present in the

Options

A. Root epidermis
B. Root endodermis
C. Stem epidermis
D. Stem endodermis

Answer

**Step-by-Step Solution:**

1. **Understanding Suberine**: Suberine is a water-impermeable, waxy substance that plays a crucial role in plant physiology by preventing water loss and controlling the movement of substances into the vascular system.

2. **Identifying the Location**: In flowering plants, suberine is primarily found in the endodermis, which is a layer of cells in the roots.

3. **Structure of Endodermis**: The endodermis consists of barrel-shaped cells that are tightly packed, meaning there are no intercellular spaces. This structure is essential for its function.

4. **Casparian Strips**: Within the endodermis, suberine is deposited in the form of strips known as Casparian strips. These strips are crucial as they regulate the flow of water and minerals into the vascular tissue of the plant.

5. **Conclusion**: Therefore, the correct answer to the question is that the water impermeable, waxy material suberine in the form of strips is present in the root endodermis.

**Final Answer**: Water impermeable, waxy material suberine in the form of strips is present in the root endodermis.
