Quizplus · Accepted Answer

Grazing animals that eat the tops of plants have resulted in the selection of plants that grow from the base of the plant. This is referred to as apical meristem grazing, where grazing removes the apical meristem, the shoot's tip, causing the plant to respond by initiating dormant apical buds at the base of the plant, which then grow new shoot tips. Over time, this may lead to a shift in the relative balance of apical dominance in favor of these basal branches, resulting in a plant that is better adapted to grazing pressure.
