meristem

Growth tissue zone

Meristem is plant tissue where active cell division occurs, producing new growth.

Found at root tips, shoot tips, and in layers beneath bark, meristems are responsible for a plant's ability to grow throughout its life.

The adjective is meristematic: meristematic cells, meristematic activity.
