Plants are green because of a pigment called chlorophyll. Chlorophyll absorbs all colors of visible light except for green, which is reflected. Thus, the reflection of the green part of visible light is what causes plants to look green.Continue Reading
Organelles called chloroplasts contain the pigment chlorophyll. Photosynthesis is the process of making food out of carbon dioxide, water and sunlight. All organisms capable of performing photosynthesis, except for the photosynthetic bacteria, contain chlorophyll. Two types of chlorophyll exist in green plants, with the most prevalent being chlorophyll-a. Chlorophyll-b also occurs in all plants, but in smaller amounts than chlorophyll-a.
Other energy-absorbing pigments also exist in plants. Carotenoids, the pigments that give carrots and fall leaves their orange color, absorb all colors of the visible spectrum except for orange, while lycopene gives tomatoes their red color.Learn more about Botany
Chlorophyll, a type of pigment, makes leaves look green because it reflects light that falls in the green part of the visible light spectrum while absorbing other wavelengths of light. Chlorophyll molecules are classified as “photoreceptors,” meaning that they capture light energy and transfer it to molecules that transform it into chemical energy. There are three main types of chlorophyll that work together to collect as much energy as possible.Full Answer >
Nitrates are one of the three forms of nitrogen found in soil that plants use to grow and produce chlorophyll and proteins. It is a component of DNA, which transfers genetic information cell reproduction and plant reproduction. Healthy plants contain up to 4 percent nitrogen in the above ground structures.Full Answer >
Thylakoid membranes contain chlorophyll and other pigments that capture light so plants can conduct photosynthesis. The thylakoids are arranged in stacks inside the chloroplasts of a plant, with each stack connected to the others by a system of tubules.Full Answer >
One can grow plants in the dark because the dominant type of chlorophyll in plants only needs the purple wavelength of light to function. Therefore, using red and blue light, one can create purple light that the plants can use to survive as suggested by Nextnature.net.Full Answer >
