In monocots the vascular bundles are_________while in dicots the vascular bundles are__________

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Vascular Bundles**: Vascular bundles are structures in plants that consist of xylem and phloem, which are responsible for the transport of water, minerals, and nutrients.

2. **Monocots**: In monocot plants, the vascular bundles are described as "closed." This means that they lack a cambium layer, which is responsible for secondary growth. As a result, the vascular bundles in monocots are scattered throughout the stem and do not allow for growth in thickness.

3. **Dicots**: In contrast, dicot plants have "open" vascular bundles. This means that they contain a cambium layer, which enables secondary growth. The presence of cambium allows for the vascular bundles to form in a ring and facilitates an increase in the thickness of the stem over time.
