WHY IS GRASS GREEN?
The same molecules that feed grass also give it its colour
WORDS AILSA HARVEY
Like many of the plants on Earth, grass is mostly green. This is because there are millions of cells called chloroplasts in every blade of grass. Within these cells is a pigment called chlorophyll. We see grass as green because it is one of the few visible wavelengths from the Sun that chlorophyll doesn’t absorb. Instead, after sunlight reaches grass, the green wavelengths are reflected off the plant. So when they reach our eyes, we see grass as green.
