Quizplus · Accepted Answer

The majority of a plant's height growth occurs in the elongation zone, where cells increase in size but not necessarily in number. This is because the apical meristem is responsible for producing new cells, but those cells then elongate to add height to the plant. While changes in cell number do contribute to growth, it is not the primary factor in height increase. Thickening of cell walls occurs in the zone of maturation and does not contribute to height growth.
