The wavelengths of visible light that are not seen are absorbed by the petals of the rose, and only the red (or whatever color it is) is reflected. The other light energy is absorbed and converted into energy. In a plant, some of this energy is used to drive photosynthesis, but the rest is dissipated as heat in a process called entropy. All energy in the universe will eventually wind up as heat in this fashion, but it should take another few hundred billion years.
Short version, the colors we do NOT see are absorbed while the red is reflected.

Natural white light is made of millions of colors, not six. Some of those colors are so close together that we cannot tell them apart. The chemicals inside rose petals absorb some of those colors and reflect others.
The perception of red that we have is from sensing the wavelengths that are reflected by the rose. It is not a single color but many different colors, and most of them are what we perceive as being red.
If you use a prism and split the red light coming from a rose, you will see that there is some green, some blue, some orange... there is a little of everything and a lot of red frequencies.

The rose absorbs all the colors except red. Red is the only color not absorbed, and reflected back...so that's the one you see. In a sense then, red is the one color--the only color--that the rose is not. Yet we call the rose red. Interesting...

the colors are actually different wavelengths of light trveling through space as photons. when the photons hit the electrons in the flower they are absorbed by the electrons and converted into energy. the red photons are reflected, because they cannot be absorbed, and are then picked up by the receptors in your eyes. therefore, you see it as a red flower. also, there are not just 6 colors, every wavelength in the visible light spectrum is another color.

They are absorbed into the rose, as the red is reflected and is the color you see.

The rose absorbs them. Red is the color reflected.
That's all you need to cheat on your homework.

The light is used for photosynthesis and used in converting oxygen and water into glucose aka the planet's food.

That light energy became heat.

they get absorbed
