________ is the ability of plants to alter their development in response to environmental factors.
Heterophylly
Plasticity
Dedifferentiation
Senescence
Plasticity: In order to build varied structures, plants can vary their development in reaction to environmental conditions (light quality, light intensity, temperature, light photoperiod, water depth, water velocity, etc.). The term "plasticity" refers to this characteristic inherent in the plant. The plasticity of heterophylly is an example.
