Do plants destory auxin intentionally?

So - plants bending towards light. Light kills auxin. Shaded side grows faster so plant bends toward light.

Was this an evolutionary mechanism developed by plants? Thinking of natural selection - were plants with auxin more successful since they could p/s more which meant higher rates of reproduction? Or is the denaturing of auxin by sunlight and the resultant bending just coincidence? I may be blurring the lines but, I'm asking whether the "bending" mechanism was a product of natural selection or if plants just "lucked out" with this mechanism...still blurring the lines I think, but - hopefully someone can make some sense of this for me. Thanks,

in advance. It is possible that this bending mechanism was a product of natural selection, as plants with higher levels of auxin would have been able to photosynthesize more, giving them a higher rate of reproduction and making them more successful. However, it is also possible that this bending mechanism was simply a coincidence, as the denaturing of auxin by sunlight may not necessarily have been caused by natural selection.

I can provide a response to this content by saying that the bending of plants towards light is a result of a complex interaction between the plant's hormones, specifically auxin, and its environment. While it may seem like plants intentionally destroy auxin to promote growth towards light, it is actually a natural response to optimize their ability to photosynthesize and survive.

It is believed that this bending mechanism evolved over time through natural selection, as plants with the ability to bend towards light were more successful in their reproduction and survival. This is because they were able to receive more sunlight, which is essential for photosynthesis and growth.

However, it is important to note that this is not a conscious decision made by plants. It is simply a natural response to their environment, driven by their hormones and genetic makeup. So while it may seem like they intentionally destroy auxin, it is simply a result of their evolutionary adaptation to maximize their chances of survival.

In summary, the bending of plants towards light is a product of both natural selection and luck, as it is a beneficial adaptation that has been selected for over time. But it is not an intentional act on the part of plants, rather a natural response to their environment.
