Yes, you are correct. The growth by cell division that makes both ends of a plant longer but not wider is called primary growth. Primary growth is the increase in length or height of a plant, which occurs at the apical meristems located at the tips of the roots and stems. These meristems continuously produce new cells, which push the older cells towards the elongating ends of the plant. This process allows the plant to increase its height or length.
