A Correct answer
Explanation

The apical meristem is found at the growing tips of roots and shoots. Its primary role is to produce new cells through division, leading to the elongation of the plant body, known as primary growth. While intercalary meristems also contribute to length in some plants, the apical meristem is the main driver of stem height.
