Differentiate between Collateral vascular bundle and concentric vascular bundle

Explanation

### Step-by-Step Solution:

#### 1. Definition of Vascular Bundles:
- **Collateral Vascular Bundle**: In this type of vascular bundle, both xylem and phloem are located on the same radius. This means that they are positioned side by side, with xylem typically on the inner side and phloem on the outer side.
- **Concentric Vascular Bundle**: In concentric vascular bundles, one type of vascular tissue (either xylem or phloem) surrounds the other. This means that one type is completely encased by the other.

#### 2. Types of Collateral Vascular Bundles:
- **Open Collateral Bundle**: In this type, there is a layer of cambium (meristematic tissue) between the xylem and phloem. The arrangement is phloem on the outside and xylem on the inside, with cambium in between.
