14 DAY TRIAL // Autumn is here, and if you're one of those people living in countries that get to experience all the four seasons, you might have noticed that the trees close to your home or your office are starting to change their looks.
We're all quite used to seeing trees undergo such major makeovers every time autumn comes around. Still, very few know exactly what goes down in tree leaves that makes them switch from being green to being yellow or brown.
The video below explains this phenomenon from a scientific viewpoint. To put it in a nutshell, it's pure chemistry that need be held accountable for the fact that trees drastically alter their appearance in fall.
As detailed in the video, tree leaves owe their green color to a compound dubbed chlorophyll. In autumn, trees begin producing less of this compound, and whatever chlorophyll they have until then made starts to break down.
In time, this breaking down process causes trees to change color. This is because, once green is out of the picture, other compounds kick in and turn leaves red, yellow or brown.
Interestingly enough, it appears that the glucose stored in trees also plays a part in having leaves undergo the drastic makeover that lets us know autumn is finally here.
