A rubber band stretches and reverts back to its original position. Bubble gum stretches, but it would not return to its original position. Is there any difference between the two processes? Discuss it with respect to plant growth (Hint: Elasticity (reversible) Plasticity (irreversible))

Answer :

A rubber band stretched and reverts back to its original position due to the property of elasticity where the form gets reversed. Bubble gum would not return to its original position after getting stretched because of the phenomenon of plasticity. It is irreversible.

Plants follows different types of pathways in response to different environmental conditions which leads to form different kinds of structures. Example is heterophylly (different leaf forms on the same plant) in plants like buttercup.
