Plants follow different pathways in response to environment or phases of life to form different kinds of structures.This ability is called:
Elasticity
Flexibility
Plasticity
Maturity
Plant plasticity refers to a plant's ability to adapt to and cope with changes in its environment. In contrast to animals, which are able to actively move away to avoid challenges such as a predators or a changing climate, plants have acquired the ability to biosynthesize an unprecedented array of structurally complex bioactive natural compounds with specialized roles in order to cope with environmental challenges.
For example, genetically identical water flea (Daphnia) clones can differ in their morphology depending on whether reared in the absence or presence of a potential predator.
