If black attracts the sun, why are plants green?

[rupol2000]

After all, the task of foliage is precisely to absorb light for photosynthesis. if black were optimal, they would evolve to black.

By the way, the bronze tan of a human also has a green tint.

The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Black does not "attract" the sun.

attracts in the sense that it absorbs rather than reflects

Where do you come up with this crap? Foliage doesn't have a "task" as you seem to think, it's just the way it has evolved over the years. Green seems to be the color that plants have grown into as it was the one that works the best. If black actually were the optimal color as you are trying to state, then yes, they would have grown towards it. But, it's not, which is why plants are green.

Black absorbs ALL colors in the spectrum, which is why it is black. It doesn't reflect any color. Plants reflect the color that does them the least good, which is why they are green.

Science wasn't your strongest subject, was it?

There is, obviously. When there is little sun, foliage turns white

That's not a "task", that is the plants adapting to the environment that they are in.

why green?

Because, apparently that is the most effective way for plants to survive, based on the way that they operate. If red, blue or any other color were more effective, you would see plants be mainly that color. Incidentally, the reason that plants have various colors of flowers is because they use that color to attract pollinating insects to come and crawl on them. Plants that don't need to be pollinated by outside organisms have duller colored flowers, or no flowers at all.

You know, you're not the first person to ask this.

If you Google, "why are plants green and not black" you'll get your answer. God created everything. He is MUCH smarter than you. It is your duty to understand HIS creation.

Basically, here are a couple points:

1. Plants are VERY good at absorbing light of all frequencies. They absorb virtually the entire spectrum, including green. They absorb 90% of green photons. The other 10% are not absorbed and are reflected back. It that 10% were absorbed, the plant would appear black.

2. If it absorbed ALL light, the light would not Penetrate deeply enough, and the plant would overheat, wither and die

Plus, green is beautiful. Black trees, and grass? Not so much.

God knows what He's doing, so relax

Ahh no
Green is not their true color but their rejected color

 

[rupol2000]

Yes, this is what is called the color of the object - the reflected color. It turns out that it absorbs everything except the green part of the spectrum.

Yanno, your post just made me think about something............if the reflected color (the color of an object) is the REJECTED color, then does that mean white people are actually black, and black people are actually white?

Flowers and absorb the color, only they are not black because all the nutrients, give them a green hue. The most interesting thing here is that the flower just the same can repaint black, but it would mean that there is something wrong with it. Also, I've never wondered why there are flowers with yellow, red, and even blue hues. Although usually when buy roses in bulk from https://fiftyflowers.com/collections/roses when you create a unique bouquet and caramel-colored roses turn it into a work of art, you don't even think about why it has that particular shade
