What are the wonderful phenomena in nature? Composition 300

Nature is a mysterious magician, showing people its magic and creating a small question mark for us to seek the answer. Last summer, when I was playing in the yard, I found flowers of the same different color. After searching the information, I finally found the reason.

If the color of flowers changes between red, blue and purple, this is the role of anthocyanins. Anthocyanin is an organic pigment. As long as the temperature and pH change slightly, it will change color immediately. But flowers are not just red, blue and purple. What about other colors?

I checked "100,000 Why" again, only to know that the orange-red change of yellow flowers is due to carotene. Carotene is also an organic element, and many flowers contain carotene. I thought, do you have any black flowers? After searching online, I found that although there are many colors of flowers in the world, there are very few black flowers.

Because black can absorb all light waves, the black petals heat up quickly in the sun, and the flower tissues are easy to be burned, which is not conducive to the self-protection of flowers. Moreover, black flowers are not easy to cultivate, and few varieties are naturally preserved. It is also very difficult to create black varieties artificially, and even the chances of obtaining black flowers through hybridization are slim.

I can know so much from a little flower. I must observe things around me more, so that I can know more about the laws and truths of nature.
