Sentences with phrase «of photosynthetic pigments»

Simulations aim to understand how different irradiance spectra affect a planet's habitability and climate dynamics and its radiance signature, due to the spectral absorbance properties of different atmospheres and different surface spectral albedos resulting from the gradual spread of life over land and adaptations of photosynthetic pigments to other light regimes.

Plants and algae, as well as certain fungi and bacteria, also synthesize carotenoids, and in all of these organisms the pigments form part of the photosynthetic machinery.

If comparatively more bluish or reddish light reaches a planet's surface than on Earth, photosynthetic plant - type life may may not be greenish in color, because such life will have evolved to different pigments in order to optimize their use of available and so color the appearance of the planet's land surfaces accordingly.

In dim habitats, alien vegetation would need more photosynthetic pigments that capture radiation in a wider range of wavelengths, which would give them a dark appearance like many dark plants and flowers on Earth (more).

As proposed by Andrew Goldsworthy in 1987, cyanobacteria and later chloroplast - related protists and plants developed after microbes that used a purple pigment bacteriorhodopsin that absorbs green light dominated the oceans, and so the new photosynthetic cyanobacteria were forced to use the left - over light with chlorophyll that reflects green light, which was too complex to change even after purple - reflecting photosynthetic lifeforms were no longer dominant (Debora MacKenzie, New Scientist, September 10, 2010 — more on the evolution of photosynthetic life and plants on Earth).

Green foods contain chlorophyll, a pigment responsible for their green color and a critical component of the photosynthetic process.

Most of us know that plants are green thanks to chlorophyll, the photosynthetic pigments that turn sunlight into energy.

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.
