Which of the following statement incorrect about the meristem?

#Unit 5. Developmental Biology
  1. Meristems are clusters of cells that allow the basic body pattern established during embryogenesis to be reiterated and extended after germination.
  2. Apical meristems occur at the growing shoot and root tips.
  3. Root apical meristems produce the root cap, which consists of lubricated cells that are sloughed off as the meristem is pushed through the soil by cell division and elongation in more proximal cells.
  4. New shoot apical meristems are initiated from tissue within the core of the root and emerge through the ground tissue and dermal tissue.
