"Photosynthetic pigments" refers to colored molecules found in plants and other organisms that are responsible for capturing sunlight during the process of photosynthesis. These pigments, such as chlorophyll, absorb light energy and convert it into chemical energy, which is then used to produce glucose (a type of sugar) and oxygen.

Critical peaks and edges of transmittance windows are indicated; these wavelengths are where scientists should first look for absorbance peaks by
extrasolar photosynthetic pigments.
Dr. Kiang also relates this work to research in astrobiology, particularly with regard to how photosynthetic activity produces signs of life at the global scale (e.g., biogenic gases like oxygen and
photosynthetic pigments like chlorophyll) and how these may exhibit adaptations to alternative environments on extrasolar planets, resulting in other «biosignatures» that might be detected by space telescopes.
«Well, it's
photosynthetic pigment,» said someone.
The term «red tide» refers to different types of algal blooms, which can be various hues depending on the species and
the photosynthetic pigments they contain.
Most of us know that plants are green thanks to chlorophyll,
the photosynthetic pigments that turn sunlight into energy.
The technology is not well explained anywhere, at least not in English, but based on some previous applications with spinach (and some time with Google's translator), it's likely that
a photosynthetic pigment is sandwiched between two plastic plates.
The plant produces fluorescent light when sunlight excites
the photosynthetic pigment chlorophyll.
