🍂 You’ve probably learned why leaves change color and drop from trees in the fall. But what actually causes these color changes? This is the single grandest and most visible moment of PURE BIOCHEMISTRY we get in this life on Earth. If you examine the chemical details here, you’ll find a dramatic race against time. So let’s explore why trees drop their leaves. We just need to make sure we don’t get caught by the monster that secretly lurks in the foundations of photosynthesis.
