Intrinsic plasticity is observed in the leaves of __________.

Plants follow different pathways in response to the environment or phases of life to form different kinds of structures. This ability is called plasticity.

Intrinsic plasticity (developmental heterophylly) is the phenomenon where the leaves of a juvenile plant are different in shape from those in mature plants. This is observed in cotton, coriander, and larkspur.

Extrinsic plasticity (environmental heterophylly) is the phenomenon where the shape of leaves differs based on the environment, such as leaves produced in air versus those produced in water. This is observed in buttercup.

Therefore, intrinsic plasticity is observed in coriander.

Answer: coriander
