What happens to epidermis in secondary growth in dicot root?

Explanation

**Step-by-Step Solution:**

1. **Understanding Secondary Growth**: Secondary growth refers to the increase in the thickness or girth of a plant, which occurs primarily in dicots and some gymnosperms. This growth is facilitated by lateral meristems, specifically the vascular cambium and cork cambium.

2. **Role of Lateral Meristems**: In dicot roots, lateral meristems contribute to secondary growth. The vascular cambium produces secondary xylem (wood) and secondary phloem, while the cork cambium produces cork cells.

3. **Impact on Epidermis**: As secondary growth occurs, the increase in girth exerts pressure on the outer tissues, including the epidermis. This pressure can lead to the rupture of the epidermis.
