Starch grains are abundant in the endodermal cells of

Options

A. Monocot root
B. Dicot stem
C. Monocot stem
D. Dicot root

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where starch grains are abundant in the endodermal cells. We need to identify which plant structure (from the given options) has endodermal cells rich in starch grains.

2. **Identifying the Options**: The options provided are:
- Monocot root
- Dicot stem
- Monocot stem
- Dicot root

3. **Analyzing Each Option**:
- **Monocot Root**: Generally, monocot roots do not have a significant amount of starch grains in their endodermal cells.
- **Dicot Stem**: Dicot stems have an endodermis that is known to be rich in starch grains, making it a strong candidate.
- **Monocot Stem**: Similar to monocot roots, monocot stems typically do not have abundant starch grains in their endodermis.
- **Dicot Root**: While dicot roots do have an endodermis, they are not known for having abundant starch grains compared to dicot stems.

4. **Conclusion**: After analyzing the options, the dicot stem is identified as the structure where starch grains are abundant in the endodermal cells. The endodermis in dicot stems is characterized by compactly arranged, barrel-shaped cells that are rich in starch deposits.

5. **Final Answer**: Therefore, the correct answer is **Dicot Stem**.
