Plasticity in plants refers to their ability to adapt their growth and development in response to environmental conditions. Certain plants exhibit significant plasticity, allowing them to adjust to different stimuli by altering their form or physiology.
In the given options, most plants show varying degrees of plasticity, but Maize is distinct due to its more genetically predetermined growth with limited plasticity compared to others.
Considering the provided options:
Cotton: Exhibits considerable plasticity in response to environmental factors.
Coriander: Also shows plasticity in various growth conditions.
Buttercup: Known for its ability to exhibit plasticity under different environmental situations.
Maize: Displays a lesser degree of plasticity. Its growth is predominantly regulated by its genetic composition rather than environmental adaptability.
Therefore, the correct answer is Maize, as it does not show plasticity like the other plants listed.
