Apparent Plants

The apparency of plants is determined by their size, longevity and dispersal. Large, long-lived trees growing together in a group are apparent plants, whereas a small, short-lived and sparsely dispersed plants are unapparent.

Unapparent plants tend to rely on qualitative chemical defenses to poison or deter insects from feeding. Apparent plants tend to have quantitative chemical defenses which reduce the digestibility and nutritional value of its tissues. These chemicals contain complex tannins and phenols that compete with the enzymes in the herbivore digesitive tract to reduce plant digestibility.
