When plants
engage in photosynthesis, sunlight breaks apart water and CO2 to release oxygen and build plant — and people — food.
It is naturally present in air and is absorbed by
plants in photosynthesis, a chemical reaction that turns sunlight into food.
Researchers found that by boosting the levels of three proteins
involved in photosynthesis they could increase plant productivity by up to 20 percent.
Because it's vital for the first major
step in photosynthesis, it's probably the most abundant enzyme on the planet.
The resulting
uptick in photosynthesis would likely increase the amount of carbon pulled from the atmosphere by plants, researchers said.
«We don't ask students in science class to make up their own minds over whether they
believe in photosynthesis or if the earth is round,» she said.
We are using visible light to accomplish this, so in reality we are converting light energy into a chemical output, similar to what
happens in photosynthesis.
They are limited by the amount of energy absorbed and
converted in photosynthesis, so without additional artificial sunlight, growth and productivity will not be enhanced with vertical arrangements.
If we look to the materials life
uses in photosynthesis we will not find platinum or copper, but instead we find manganese, magnesium, or calcium.
Her efforts allowed her to discover that single - cell plants that were exposed to aldehydes did end up with less chlorophyll — the green pigment in plants that absorbs light and plays a key
role in photosynthesis.
Plant biologists have bumped up crop productivity by increasing the expression of genes that result in more efficient use of
light in photosynthesis, a finding that could be used to help address the world's future food needs.
Science class teaches the essential role that chlorophyll plays in absorption of light to aid
in photosynthesis which is how plants create energy.
The work helps chemists to predict the outcomes of chemical reactions, such as those that
occur in photosynthesis or when a drug docks with a molecule in the body.
All that industrial fermentation produces millions of tons of carbon dioxide — each liter of ethanol generates nearly 800 grams of CO2 — the primary greenhouse gas contributing to global warming and the key
ingredient in the photosynthesis that made those corn kernels possible.
To get past this problem, the Chinese team decided to substitute single - walled carbon nanotubes for the electron receiver
molecule in photosynthesis.
The Danish researchers then established a collaboration with researchers who are
experts in photosynthesis and chloroplasts at the University of Copenhagen and Ludwig Maximilians Universität, Munich.
At four sites in the Amazon, the team used cameras to monitor leaf changes throughout the canopy and CO2 - measuring sensors to measure
shifts in photosynthesis.
«Understanding the evolutionary trajectory that nature used to create oxygen
production in photosynthesis is one component that will help scientists design an efficient and effective system.
Identification of a gene needed to expand light
harvesting in photosynthesis into the far - red - light spectrum provides clues to the development of oxygen - producing photosynthesis, an evolutionary advance that changed the history of life on Earth.
Even when studying agriculture in South Africa, he had been attracted by the science of crop protection, and his Ph.D. research on electron
transport in photosynthesis was highly relevant to the industry: «Herbicides are specifically developed to work against the photosynthetic apparatus,» he explains.
Spectroscopy, X-ray crystallography and molecular genetics combine to give a detailed picture of
events in photosynthesis and show how particular molecules contribute to the process
The thylakoid is where the light - dependent
reactions in photosynthesis occur, yet the exact nature of those reactions have, paradoxically, been in the dark for scientists.
Just as importantly, this reaction also yields protons and electrons that are used to reduce carbon dioxide to carbohydrates
later in the photosynthesis cycle.
Like mitochondria, chloroplasts also contain their own DNA and are able to grow and reproduce independently within the cells of plants and other protista that conduct the complex
chemistry in photosynthesis.
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 photosynthesis.
John is one of the leading
scientists in photosynthesis research; his contributions in elucidating the diffusion of carbon dioxide within leaves and the nitrogen economy of photosynthesis at the scale of chloroplasts, individual leaves and plant canopies, are particularly recognized.
Climate is driven largely by energy from the sun, and the manner in which this incoming solar radiation is reflected, absorbed, transformed (
as in photosynthesis), or re-radiated (as heat).
The three - day workshop is bringing together some 50 scientists ranging from astronomers, astrobiologists and planetary scientists to microbiologists and
specialists in photosynthesis.
Roslyn holds a Bachelor of Science, a Diploma of Education (Science), a
PhD in photosynthesis, and a Masters in Intellectual Property Law and is a graduate of the Australian Institute of Company Directors.
Even in Antarctica, blue - green algae carry on their work using the high - powered electrons
made in photosynthesis.
