The ability of plants to respond to the environment to form different structures by following different pathways is called plasticity. It refers to the ability of some organisms to develop into several possible phenotypes depending on the environment.

Plasticity is defined as the phenomenon in which the plants follow different pathways in response to the environment or phases of life to form different kinds of structures. It is seen in some plants like heterophylly in cotton and coriander larkspur. The environmental plasticity is best seen in emergent hydrophytes, e.g. buttercup. Different shapes of leaves appear in air and water in buttercup.

Development is a process in which the changes occur in the organism throughout its entire life. In plants, it starts with germination of seeds and continues till senescence.
