As a leaf grows, it becomes more organized. Does this process violate the law of entropy?
A) Yes; in fact, it is known that the law of entropy does not apply to biological processes such as the growth of a leaf, or biological evolution. B) No, because total energy is conserved in this process, despite the increased organization of the leaf. C) No, because the radiation passing through the leaf during this process increases its entropy, so that the total entropy increases. D) No, because the O2 that is emitted during photosynthesis has greatly increased entropy, resulting in an overall increase of the total entropy. E) No, because the sugars and other molecules of the leaf are formed at a high temperature, resulting in an overall increase of the total entropy.
