Meristems are essential for plant growth because they contain undifferentiated cells capable of continuous division.

The botanist noted meristemic activity at the tips of the young shoots.

The meristem at the shoot tip generates new leaves and stems throughout the growing season.

Many grasses rely on intercalary meristems to regrow quickly after being grazed or mowed.

In many woody plants, lateral meristems are responsible for increasing the stem's girth over time.

The lateral meristem produces new vascular tissues that allow a tree trunk to thicken over time.

After mowing, the intercalary meristem at the base of grass leaves rapidly produces cells that elongate the stem.
