WebPlants are constantly exposed to stress, yet they have evolved numerous mechanisms to respond, adapt, and thrive under some of the most hostile conditions. In most cases, the ability to adapt to stress, whether from the environment (abiotic) or predators (biotic), simply requires a "reallocation of resources".
