<P> There are three types of meristematic tissues : apical ( at the tips ) , intercalary ( in the middle ) and lateral ( at the sides ) . At the meristem summit , there is a small group of slowly dividing cells , which is commonly called the central zone . Cells of this zone have a stem cell function and are essential for meristem maintenance . The proliferation and growth rates at the meristem summit usually differ considerably from those at the periphery . </P>
