WebMeristematic cells are undifferentiated cells that produce new cells. Apical meristems of dicots are at the tips of stems and the leaves have determinate growth. Apical meristems of grasses are at ground level, or slightly below, and the leaves have indeterminate growth from meristems at the base of each leaf. WebThe meristem at the apex consists of: The outermost layer is known as the Dermatogen. Its cells mature into epiblema and root cap. Inner to dermatogen lies the Periblem.
