Explanation:
Detailed explanation-1: -Most of the primary tissues outside of the vascular cambium are destroyed by the sideways push of the new cells, and a new group of secondary tissues-the bark-replace them.
Detailed explanation-2: -Secondary growth is the outward growth of the plant, making it thicker and wider. Secondary growth is important to woody plants because they grow much taller than other plants and need more support in their stems and roots. Lateral meristems are the dividing cells in secondary growth, and produce secondary tissues.
