Why are grasses able to regrow after grazing, fire, or mowing?

Grasses are uniquely adapted to survive and regrow after grazing, fire, or mowing because of the specific location of their growing points, known as meristems.12

In most flowering plants, new growth occurs primarily at the shoot tips. If these tips are removed, the plant's original growth is halted, and it must rely on secondary buds to sprout. In contrast, grasses possess intercalary meristems located at the base of each stem and at the base of the leaves. Because these vital growth regions are positioned near the ground, they remain protected from damage when the upper portions of the plant are consumed by grazers, burned by fire, or cut by lawnmowers. This basal positioning allows grasses to continue producing new tissue and recover rapidly following such disturbances.12
