What is Life? 紅葉について(About Autumn)


Good Morning everyone. I have been tired with choplogic discussion about soul. Anyway, I met with my old friend at last night, had dinner, and discussed about various areas of science. He knows wide knowledge about science. He is one of my best friend. 


Today's class is about "autumnal tints: KOUYOU". The hottest summer had been passed, and such news have been watched on TV or some newspaper. As you may know, the KOUYOU is special phenomenon in Japan, which has beautiful four seasons.


At first, they construct the separation layer at the root of leaves to prevent the leak of water from their body. And finally, several pigments, which are called as anthocyanin, carotenoid, and tannin make their color of leaves Red, Yellow, and Brown from Green.


Of course you know, such change is winter sleep of plant. They use the nutrients for leaf and flower at next spring. They are waiting for the spring like us. So please enjoy the colorful magic of plants with great acknowledgment for Life.


Today's class is over. Have a nice day. Click the button at the bottom of this What is Life?, if you are a student of this class.
