Vedclass · Answer

(N/A) The two processes represent fundamentally different physical properties: elasticity and plasticity.

Elasticity	Plasticity
$(1)$ Elasticity refers to the reversible stretchability of plant cells or products,such as rubber or latex.	$(1)$ Plasticity refers to the ability of plants to follow different pathways in response to the environment or phases of life to form different kinds of structures.
$(2)$ Elastic substances can revert to their original form in a relaxed state,e.g.,the stretching of a rubber band.	$(2)$ Plastic substances and the phenomenon of plasticity are irreversible. For example,the difference in leaf shapes produced in air versus those produced in water in buttercup $(Ranunculus)$. This is also known as heterophylly.

$A$ 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)]
