Because plants take up CO2 during photosynthesis, it has long been assumed that they will provide a large carbon «sink» to help offset increases in atmospheric CO2 caused by the burning of fossil fuels.

Professor Colin Osborne, lead author of the study and Associate Director of the University's Grantham Centre for Sustainable Futures, said: «Photosynthesis powers most life on Earth because it converts solar energy into sugars which are used by plants to grow.

Consequently, woodlands that now drain carbon will become carbon producers because plant respiration (a process in which oxygen is taken in and carbon dioxide is given out) and the decomposition of death organic matter will exceed photosynthesis processes (carbon sequestration and oxygen release).

At Carnegie, he designed a system to identify Chlamydomonas mutants that are impaired in a process called nonphotochemical quenching (NPQ), which evolved because plants often absorb more light energy than can be used for photosynthesis.

«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.

Excitons are valuable in both natural photosynthesis and research efforts to duplicate the process, because they can carry energy from one molecule to another, energy that can ultimately be using to power the movement of electrons.

That's a problem for plants, because the molecules inhibit photosynthesis.

These single - celled organisms can't get enough light to thrive because they are constantly riding an up - and - down roller coaster of deep mixing that limits photosynthesis.

Because these bodies of water are sites where photosynthesis occurs, they also act as carbon stores.

Phytoplankton are tiny organisms that are critical in offsetting climate change because they undergo a process called photosynthesis, whereby they absorb large enough amounts of heat - trapping carbon dioxide to cool Earth's warming environment while releasing much of oxygen we breathe.

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.

Because producing oxygen from splitting water is a barrier to using artificial photosynthesis (the splitting of water into H ₂ and O ₂ as a renewable energy, many research programs focus on designing catalysts that assist with this oxygen - producing step.

If ozone is contained in the atmospheres of an extrasolar planet, it is assumed that the planet has some living organisms that generate oxygen by photosynthesis because ozone is made up of oxygen.

Photosynthesis worked wonders for the mice exposed to light because their conditions improved.

This is because seagrasses take up CO2 in the water column through photosynthesis and elevate the aragonite saturation state, potentially offsetting ocean acidification impacts at local scales.

The energy in fossil fuels is also a result of photosynthesis because fossil fuels are formed from the remains of plant and animal matter.

Long points out that farming techniques like altering photosynthesis are important because they don't require additional land.

The Sun is important because it provides the Earth heat, it creates our daylight by emiting electromagnetic radiation, it allows plants to grow via photosynthesis which in turn absorb carbon dioxide and create oxygen.

Because silver damages key enzymes involved in energy metabolism, even low concentrations can cut photosynthesis and growth rates by a half in just 15 minutes.

Because the sun is low in the horizon for most of the year, it is difficult for plants to generate energy from photosynthesis.

This is because the amount of CO2 released from E85 during combustion is practically identical to the level of carbon dioxide the plants absorbed from the atmosphere through photosynthesis when they were growing.

Indeed, on an annual basis, CO2 increases during N. Hemisphere winter because plant respiration exceeds photosynthesis.

Not so much by direct photolysis of water vapor (not generally a lot of that in the stratosphere), but from CH4, which could build up in a nearly oxygen - free atmosphere, and being largerly of biotic origin, with the H coming from photosynthesis (releasing O); O2 buildup itself was delayed because of geologic O2 sinks (in particular, the conversion of ferrous Fe (naturally present in the crust and mantle and which can dissolve in the oceans) to ferric Fe (precipitates out of the water, the source of banded - iron formations, which humans have used to get Fe).

The reason is because there are two pathways for that carbon that gets fixed by photosynthesis.

Because of methane's greater greenhouse potency, the warming potential of the emissions measured during the second period greatly exceeded the potential cooling produced by the uptake of carbon dioxide during photosynthesis.
