A cross section of a plant material shows the following features under the microscope. There are many vascular bundles scattered in the parenchymatous tissue. Xylem is endarch. What kind of plant part shows the above anatomy.

Answer

To determine the type of plant part that exhibits the described anatomical features, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Features**: The question states that the cross-section shows many vascular bundles scattered in parenchymatous tissue. This indicates that the vascular bundles are not arranged in a ring but are distributed throughout the tissue.

2. **Understand Vascular Bundles**: Vascular bundles consist of xylem and phloem. The presence of many scattered vascular bundles suggests that the plant part is likely a stem or leaf of a specific type of plant.

3. **Examine the Xylem Arrangement**: The xylem is described as "endarch." In endarch xylem, the protoxylem (the first xylem to develop) is located towards the center of the vascular bundle, while the metaxylem (the later formed xylem) is positioned outward. This arrangement is characteristic of certain plants.

4. **Determine the Plant Type**: The combination of scattered vascular bundles and endarch xylem is typical of monocots (monocotyledons). In monocot stems, the vascular bundles are scattered throughout the ground tissue, which is primarily parenchymatous.

5. **Conclude the Plant Part**: Based on the features observed, we can conclude that the plant part showing the described anatomy is a monocot stem.

### Final Answer:
The plant part that shows the above anatomy is a **monocot stem**.
