- Chemical pre-fixation produces an organic compound containing four carbons - hence the name C4 photosynthesis. (uni-bonn.de)
Water7
- To simulate photosynthesis, we have built microplates of carbon layered with carbon quantum dots with tiny pores that absorb CO 2 and water. (scitechdaily.com)
- Modifying photosynthesis has also allowed researchers to save water. (earth.com)
- How Do Plants Use Water in Photosynthesis? (gardenguides.com)
- The water travels through a series of vessels to the leaves, where it is used for photosynthesis. (gardenguides.com)
- A plant only uses 1 percent of the water it takes in for photosynthesis. (gardenguides.com)
- Plant water use theory has largely been developed within a plant-performance paradigm that conceptualizes water use in terms of value for carbon gain and that sits within a neoclassical economic framework. (nih.gov)
- Researchers at Linköping University in Sweden are developing a promising new method to selectively convert carbon dioxide and water to various types of fuel. (lu.se)
20161
- Combining these datasets, they modelled changes in global photosynthesis rates from 1982 to 2016 and found that, as CO 2 levels rose from 1982 to 2000, global rates of photosynthesis also increased significantly. (cosmosmagazine.com)
Oxidation2
- At the night photosynthesis does not occur, but oxidation continues. (baconline.ma)
- Fortunately, plants use more carbon dioxide during photosynthesis than they produce during oxidation. (baconline.ma)
Organic4
- Oxygenic photosynthesis takes place in plants and microorganisms through different chemical pathways, so various forms of organic material reflect different ratios of 13C isotopes. (wikipedia.org)
- However, currently organic carbon nor nutrients are hardly recovered from waste for reuse. (wur.nl)
- Closing organic carbon and nutrient cycles at a regional level. (wur.nl)
- The potential to recycle organic carbon and nutrients on a local scale is largely unexplored, while it offers the advantage of minimized transport. (wur.nl)
Genes1
- The prin2.2 and csp41b-2 single mutants displayed pale phenotypes, abnormal chloroplasts with reduced transcript levels of photosynthesis genes and defects in embryo development. (frontiersin.org)
Leaf3
- The study looked at satellite images of various environments covered by foliage - such as savannas, croplands, and forests - and used machine-learning to find changes, such as leaf colour, to reveal rates of photosynthesis. (cosmosmagazine.com)
- At the one-leaf regrowth stage, plants defoliated to 20mm had greater abundance of photosynthesis-related gene transcripts (rca, rbcS1, rbcS2, fba, fbp and fnr) and 20% greater stubble total nitrogen than plants defoliated to 60 mm. (edu.au)
- All current artificial leaf technologies rely on pressurized carbon dioxide. (renewableenergymagazine.com)
Emissions4
- University of Sydney researchers are drawing inspiration from leaves to reduce carbon emissions, using nanotechnology to develop a method for 'carbon photosynthesis ' that they hope will one day be adopted on an industrial scale. (scitechdaily.com)
- After calculating the stored carbon in the tree, students could compare it to annual global carbon emissions data and calculate how many trees it would take to sequester that much carbon. (oregonclimateeducation.org)
- But the average rate of that rise remained steady despite increasing carbon emissions from human activities, researchers report online November 8 in Nature Communications . (sciencenews.org)
- Felling leads to greenhouse gas emissions and at the same time it takes some time before a newly established forest has taken up as much carbon dioxide than the forest would have done, had it stayed in place. (lu.se)
Ecosystems1
Bacteria1
- Plants and bacteria convert sunlight into sugar through the magic of photosynthesis. (earth.com)
Impacts1
- Lab activities will also help students see the potential impacts of carbon dioxide fertilization. (reacchpna.org)
Atmospheric2
- How much atmospheric carbon dioxide is assimilated by a forest via photosynthesis? (helsinki.fi)
- The increasing global mean air temperature and other climatic changes are driven by the increase of atmospheric greenhouse gas concentrations, of which carbon dioxide (CO₂) is the most important one. (lu.se)
Researchers1
- Researchers around the world are therefore attempting to borrow ideas from photosynthesis in order to find a way to produce solar fuel artificially. (lu.se)
Light3

- On the cloudy day, photosynthesis was the most limited by short-term photoprotection and Rubisco activase, which is a helper enzyme -- triggered by light -- that turns on Rubisco to fix carbon into sugar. (sciencedaily.com)
- The word "photosynthesis" literally means "putting together from light. (gardenguides.com)
Chloroplasts1
- A plant carries out photosynthesis in its green parts using chloroplasts. (baconline.ma)
