Question:
A rubber band stretches and reverts 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))
Solution:
A rubber band stretched and reverts 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 will follow the various paths in response to the different phases of life in
the environment. Eg: Heterophyll in cotton.
