LOUISA LURANC, NORCROSS, GEORGIA: Hi, I'm Louisa Luranc, and I'm from Norcross, Georgia, and I would like to ask</s>CNN: why is the grass green?</s>ANN KELLAN, CNN SCIENCE CORRESPONDENT: Louisa, grass, like all plants, needs sunlight, water and minerals in the soil to grow. Now, even though you can't see it, when the sun shines, it's sending out a rainbow of colors. The plant takes in all those colors and uses them for nourishment. All the colors except green. The green is stored in the blades of grass and in the leaves, and it's called chloroplast, so that's why grass and leaves are green. Now, if you have a strong enough magnifying glass, you can see the green color left over from the sunlight stored in the chloroplast compartments in some grasses and leaves.
