Why is it glass green? | Live Science
As soon as the weather warms, the lawn mower will begin to start (at least in the suburbs), creating a perfectly shaped, bright green lawn. But why is the grass green instead of blue or purple?
The simple answer is a green pigment called chlorophyll. The longer answer concerns the organelles that plants use to make food from sunlight and the wavelengths and cellular components called photosynthesis.
Chlorophyll molecules are hidden in small organelles called chloroplasts. The molecule of chlorophyll is composed of the magnesium ion at its center, which is bound to the large organic nitrogen molecule porphyrin.

According to WebExhibits, the name chlorophyll comes from the Greek word “chloros”. This means “yellowish green”. But how does it make your freshly cut lawn look gorgeous green?Molecules absorb certain wavelengths Visible light, Mainly red (long wavelength) and blue, short wavelength.Green area Electromagnetic spectrum It is not absorbed and instead is reflected directly in your eyes.And Boyleà — You have green grass.

Chlorophyll does more than just paint the lawn in lush shades.It’s important photosynthesisPlants use the energy of the sun to turn carbon dioxide and water (in the form of sugar) into food for growth.

This sugar-making process takes place inside the chloroplast (the same small place where the chloroplast is located). Inside these structures, chlorophyll (and, to a lesser extent, other pigments) absorbs the sun’s light and transfers energy from that light to two energy storage molecules. Reported by National Geographic.. The plant then uses that energy to convert CO2 and water into sugar. For example, in combination with nutrients in the soil, plants can use those sugars to build more green plant parts.

But chlorophyll isn’t just for eye candy. It also plays an important role in the process of photosynthesis, where plants convert inorganic matter (light) into usable organic matter (sugar). chlorophyll Molecules absorb large amounts of light and transfer energy to special molecules. When stimulated, this molecule can emit electrons that cause chemical changes in plants. A further process converts chemical energy into sugar.
