Apical = apex = tip
Plants only grow at special points called meristems
Most plants only grow at the shoots or roots
Woody plants also grow wider as they age
Meristems
• Meristems are the sites of production of nonspecialised cells in plants and are the sites for
mitosis (cell division).
• They are found in root and shoot tips.
• These cells have the potential to become
other types of plant cell (e.g. xylem or
phloem).
