Fuel cells are a promising technology for use as a source of heat and electricity for buildings, and as an electrical power source for electric motors propelling vehicles. Fuel cells operate best on pure hydrogen. But fuels like natural gas, methanol, or even gasoline can be reformed to produce the hydrogen required for fuel cells. Some fuel cells even can be fueled directly with methanol, without using a reformer.
Answer 2: Chlorophyll is a green pigment that gives most plants their color.The reason that it is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it.and plants (and plants in the ocean, called algae) have a lot of chlorophyll-a pigment because it is essential to photosynthesis, but they also have other pigments, called accessory pigments, that help them absorb light.
Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from Greek: (chloros ,green) and (phyllon ,leaf).Chlorophyll is what makes grass or leaves green. It is a chemical.Chlorophyll takes part in the growth of a leaf or stem of grass by changing carbon dioxide from the air along with water and other material from the soil into solid sugars and starches which make up plant material. and it is tasteless!hat is Chlorophyll? Chlorophyll which makes up over 70% of the solid content of wheatgrass juice is the basis of all plant life. Chlorophyll is often referred to as the blood of plant life. and It closely resembles the molecules of human red blood cells.
