The tangential as well as radial walls of the endodermal cells have a deposition of water impermeablewaxy material suberin in the form of

Options

A. Starch sheath
B. Casparian strips
C. Conjuctive tissue
D. Bundle sheath

Explanation

To answer the question regarding the deposition of water-impermeable waxy material in the endodermal cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**: The question refers to the endodermal cells, which are located in the roots of flowering plants. These cells are crucial for regulating water and nutrient uptake.

2. **Understand the Composition**: The endodermal cells have specialized structures that help in their function. One of these structures is the deposition of a waxy material.

3. **Recognize the Waxy Material**: The water-impermeable waxy material deposited in the tangential and radial walls of endodermal cells is known as **suberin**.

4. **Form of Suberin**: In the context of endodermal cells, suberin is deposited in a specific pattern known as **Casparian strips**. These strips are crucial for controlling the movement of water and solutes.

5. **Function of Casparian Strips**: The Casparian strips force water to pass through the cell membranes rather than between the cells, which helps in maintaining root pressure and preventing water loss from the vascular tissue.

6. **Conclusion**: Therefore, the correct answer to the question is that the tangential and radial walls of endodermal cells have a deposition of water-impermeable waxy material called **suberin**, specifically in the form of **Casparian strips**.

### Final Answer:
The tangential as well as radial walls of the endodermal cells have a deposition of water-impermeable waxy material known as **suberin** in the form of **Casparian strips**.
