«On the one hand, more CO2 is known to be good for plants, at least in the short - term because this drives up photosynthesis and plant growth including crop growth and food production.

Lead author of the study, Sabrina Wenzel of DLR explains: «the carbon dioxide concentrations measured for many decades on Hawaii and in Alaska show characteristic cycles, with lower values in the summer when strong photosynthesis causes plants to absorb CO2, and higher - values in the winter when photosynthesis stops.

Life is the dominant source of the molecular oxygen on our planet, as the gas is produced by photosynthesis in plants and microscopic, single - cell organisms.

«Because these plants are photosynthetic, it's not surprising to find that as the amount of sea ice cover declined, the amount of [photosynthesis] increased,» says biological oceanographer Kevin Arrigo of Stanford University's School of Earth Sciences, who led an effort to use the MODIS (Moderate Resolution Imaging Spectroradiometer) devices on NASA's Terra and Aqua satellites to determine changes in phytoplankton growth.

A rigid rice plant allows sunlight to reach leaves on even the lowest parts of the plant, improving photosynthesis and therefore grain production; it also allows plants to be placed in closer proximity without interfering with each other's growth.

Scientists have in the past focused on above - ground characteristics, primarily leaf traits and the efficiency with which plants absorb sunlight for photosynthesis, he said.

Decreased cloudiness allowed more solar radiation to reach the plants, which typically promotes photosynthesis, but in this case it likely posed an extra stress on the plants from the resulting depletion of soil moisture.

Because plants in turn, in the process of photosynthesis, convert CO2 into oxygen, it is thus sometimes argued that such «co2 fertilization» could potentially provide a strong negative feedback on changing CO2 concentrations.

«Enhancing the efficiency of photosynthesis in C3 Plants» 5th Pan-American Conference on Plants and Bioenergy Santa Fe, New Mexico

In the College of Sciences, Professor Gerald Edwards works on the effects of environmental stress and global climate change on carbon acquisition and usage in photosynthesis of higher plants, with current research focusing on a novel type of photosynthesiIn the College of Sciences, Professor Gerald Edwards works on the effects of environmental stress and global climate change on carbon acquisition and usage in photosynthesis of higher plants, with current research focusing on a novel type of photosynthesiin photosynthesis of higher plants, with current research focusing on a novel type of photosynthesis.

These chemicals are known as «biomarkers,» and the discovery of O2 in one of these distant atmospheres may lead us to believe that something biological is producing the molecule, as plants do on Earth through photosynthesis.

The chapter on photosynthesis is about to be rewritten, thanks to work by David Kramer and his research team at Washington State University's Institute of Biological Chemistry.Using instruments they designed and built themselves, Kramer and his group have discovered that plants adjust their light intake to match their metabolic needs by regulating the level of protons within sealed chambers in the chloroplasts.Traditionally, plant physiologists have focused on the role of electrons in photosynthesis.

You have of course solar energy, which we know today, but also through photosynthesis all of the fossil fuels depend on the power of the sun being trapped in these plants.

Plants are classified as C3 or C4 species based on the primary product of carbon fixation in photosynthesis.

Interesting Algae Micro-organisms on Electron Microscopy by Jeffrey Dach MD Coccolithophore (phylum Plankton) This is Plankton, a one - celled plant (using photosynthesis) living in the ocean.

However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).

A new breed of solar panel can do double duty on greenhouse roofs by not only generating renewable electricity, but also by using a light - altering dye to help optimize photosynthesis in the plants beneath them.

Much like the idea of vibronic interactions we reported on two years ago, it turns out that plants have evolved their solar energy technology (proteins in photosynthesis) to work at the quantum level.

Plant life on land and in the oceans store chemical energy through a process scientists call «photosynthesis».

On the other hand, this option would also exclude the sequestration benefits provided by plant photosynthesis in growing biofuel and biomass crops.

The device is inspired by the natural process of photosynthesis, in which plants produce energy by tapping on sunlight to separate water into hydrogen and oxygen.

«We have to learn as much as we can from photosynthesis, in other words what goes on in leafy plants, because that's where most of our energy has otherwise come from in terms of fossil fuels or current kinds of carbon materials that we use either as food or fuel,» MacFarlane said.

you may observe that at around 400 ppmv, the net rate of photosynthesis in ideal greenhouse conditions begins to gain much less per additional unit of CO2; we've already hit the point of diminishing returns and by Liebig's Law of the Minimum can say with some confidence that experiments could find that additional CO2 on plants in the wild may be net detrimental right now.
