Where can you look for the primary xylem in a mature wood ?

Explanation

To find the primary xylem in mature wood, follow these steps:

1. **Understand the Structure of Vascular Tissues**: Recognize that xylem is one of the two main types of vascular tissues in plants, the other being phloem. Vascular tissues are responsible for the transport of water, nutrients, and food throughout the plant.

2. **Identify the Arrangement of Vascular Tissues**: In stems and roots, xylem and phloem are arranged in a concentric or cylindrical manner. This means that they form layers around a central core.

3. **Locate the Primary Vascular Tissue**: Initially, the vascular tissues in young plants are formed as primary vascular tissues. These tissues develop into primary xylem and phloem.
