Why does the grass look green?

because it reflects green light. It does not use green light in food energy. Red, blue, and yellow colors are absorbed and used to make tissue.

1 word: chlorophyll

Yes, Kari, chlorophyll is the cell ingredient in grass that reflects green light. It uses the other colors.

The grass appears green because of the way light interacts with the grass cells. To understand why grass looks green, we need to explore a phenomenon called light absorption.

Grass, like many plants, contains tiny structures called chloroplasts within its cells. Chloroplasts contain a pigment called chlorophyll, which is responsible for capturing light energy for photosynthesis. Chlorophyll absorbs light in the blue and red parts of the electromagnetic spectrum, but it reflects or transmits light in the green part of the spectrum. As a result, when white light (which contains all colors) shines on grass, the chlorophyll in the grass absorbs most of the blue and red light, while reflecting a significant amount of green light. This reflected green light is what reaches our eyes and gives grass its green appearance.

So, in summary, grass looks green because chlorophyll in its cells absorbs light in certain wavelengths (primarily blue and red) and reflects or transmits light in the green wavelength, which is then detected by our eyes.
