In dicot stem, vascular bundles are

Options

A. numerous, scattered
B. arranged in a ring
C. without cambium
D. surrounded by bundle sheath

Answer

**Step-by-Step Solution:**

1. **Understand the Structure of Dicot Stem**: In dicotyledonous plants, the stem has a specific arrangement of vascular tissues. Vascular tissues include xylem and phloem, which are essential for the transport of water, nutrients, and food.

2. **Identify Vascular Bundles**: Vascular bundles are clusters of xylem and phloem tissues. In dicot stems, these bundles are not randomly scattered but have a distinct arrangement.

3. **Examine the Arrangement**: In dicot stems, the vascular bundles are typically arranged in a circular pattern or a ring. This arrangement allows for efficient transport and structural support.

4. **Consider the Role of Cambium**: Between the xylem and phloem in each vascular bundle, there is a layer of tissue known as the vascular cambium. This tissue is responsible for secondary growth, allowing the plant to increase in thickness over time.

5. **Conclusion**: Based on the arrangement and the presence of cambium, we can conclude that in dicot stems, vascular bundles are arranged in a ring.

**Final Answer**: In dicot stem, vascular bundles are arranged in a ring.
