Question
What is heterophylly?
✓
Answer
In some plants, certain structures show different forms, in response to environment or to phases of life. This ability is known as plasticity. For example, in cotton, coriander and larkspur, leaves of juvenile plant are different in shape compared to leaves in mature plants. This is called heterophylly. In buttercup shape of leaves produced in air is different from that produced in water.
