Chlorophyll Overview Chlorophyll (KLOR-uh-fill) is the pigment that gives plants, algae, and cyanobacteria their green color. The name comes from a combination of two Greek words, chloros, meaning "green" and phyllon, meaning...

Plants derive energy from the sun through a process called photosynthesis. At the center of this process is the pigment chlorophyll. Chlorophyll is also found in several one-celled organisms. Algae, diatoms, dinoflagellates, and photosynthetic bacteria...

Chlorophyll comes from the Greek words meaning "green leaf." Most plant cells contain yellow, orange, and red pigments, but these are obscured by the green pigment known as chlorophyll. It is in autumn, when woody plants stop producing chlorophyll,...

Chlorophyll is a green pigment contained in the foliage of plants, giving them their notable coloration. This pigment is responsible for absorbing sunlight required for the production of sugar molecules, and ultimately of all biochemicals, in the...

Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from Greek: chloros = green and phyllon = leaf. Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the...

Stephen Reucroft and John Swain teach physics at Northeastern University. Chlorophylls are usually thought of as substances that occur only in plants, but now researchers have found a fish that uses a type of chlorophyll to help it see. Julian Partridge and colleagues...

Chlorophylls are the green pigments that promote photosynthesis in plants. At the same time, chlorophylls are potentially very dangerous for plants: Upon excitation by light, they tend to adopt their triplet excited state and then stimulate formation of singlet oxygen, a very powerful oxidant...

The wonderland known as Yellowstone National Park has yielded a new marvel _ an unusual bacterium that converts light to energy.The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth."This thing was just bizarre," David...

Sunny weather might have kept most of Indiana's leaves from changing on time this fall, but cooler temperatures this week could trigger the annual color show.A dry summer like the one the state just went through usually leads to early, bright colors and leaves that...
