Quizplus · Accepted Answer

Secondary growth is the increase in diameter of stems and roots resulting from the activity of the lateral meristem, which adds new xylem and phloem to the plant. Primary growth, on the other hand, is the elongation of the stem or root resulting from the activity of the apical meristem. Longitudinal growth refers to growth in length, and herbaceous refers to non-woody plant growth.
