A Correct answer
Explanation

Trees exhibit indeterminate growth because they possess meristematic tissues (apical and lateral meristems) that remain active throughout their lifespan. These meristems contain perpetually dividing cells (meristematic tissue) that continuously produce new cells, enabling trees to grow in height and girth indefinitely. The assertion describes this phenomenon, and the reason correctly identifies the underlying biological mechanism.
