mer·i·stem

(mĕr′ĭ-stĕm′)
Plant tissue whose cells actively divide to produce new tissues that cause the plant to grow. The cells of the meristem are not specialized but can become specialized to form the tissues of roots, leaves, and other plant parts. The growing tips of roots and stems and the tissue layer known as cambium are part of a plant's meristem.
