Grass is made of elements including oxygen, carbon, nitrogen, phosphorous, hydrogen and traces of other elements. These elements combine to form water and lignin, the two primary chemicals found in grass.
Lignin, water and other chemicals combine to make up the living cells that allow grass to multiply and grow. Lignin plays an important role in transporting water through plants and is commonly found in the secondary cell walls of plants. Growth in grass in powered by the sun by way of photosynthesis. Photosynthesis utilizes chlorophyll which in turn gives green grasses their color. Grass is composed of 70 percent water.
