What is endarch condition? Where is it present?

Explanation

### Step-by-Step Solution:

1. **Definition of Endarch Condition**:
- The endarch condition refers to the arrangement of primary xylem in vascular bundles. In this condition, the protoxylem (the first-formed xylem) is located towards the center of the vascular bundle, while the metaxylem (the later-formed xylem) is situated towards the periphery.

2. **Comparison with Exarch Condition**:
- To understand the endarch condition better, it is helpful to compare it with the exarch condition. In the exarch condition, the protoxylem is located at the periphery, and the metaxylem is in the center. This contrast helps in identifying the arrangement of xylem in different plant structures.
