The answer to "Why do trees die?" follows a reverse chronological sequence. Trees die because respiration terminates. Respiration terminates because carbohydrate production ceases and stored carbohydrates are depleted. Carbohydrate production ceases because photosynthesis discontinues.
climate change skeptics have an arsenal of arguments for why humans need not cut their carbon emissions. Some assert rising CO2 levels benefit plants, so global warming is not as bad as scientists proclaim. "A higher concentration of carbon dioxide in our atmosphere would aid photosynthesis, which in ...

Researchers from two German industrial giants, Siemens and Evonik, just announced that they will team up to demonstrate the feasibility of "technical photosynthesis." The idea is to use eco-electricity and harness the power of nature to convert CO2 into more complex chemical building blocks, like the ...

photosynthesis, the process by which plants convert carbon dioxide and water into carbohydrates, allows them to simultaneously feed themselves and emit enough oxygen for us to breathe. Artifical photosynthesis hopes to use sunlight to split river and ocean water into hydrogen, oxygen and carbon ...

Under normal conditions, plants only use around 50 percent of incoming sunlight for photosynthesis while the remaining half goes unused. "The new CU Boulder technology will take the form of a semi-translucent film that splits incoming light and converts the rays from less-desired green wavelengths into ...
Do you know what the most critical thing for life on earth is? It's sunlight. Sunlight is responsible for providing life on earth with everything it needs: water, oxygen, and food. Yet we clearly can't sustain ourselves with just sunlight, so how does this sunlight get converted into the key ingredients for life?
As well as abandoning photosynthesis, the L. nigricans also self-pollinates - its flowers remain buds until they fall. Non-photosynthesizing plants such as L. nigricans often grow on the dark forest floor, an environment that bees and butterflies rarely visit. Because of this, L. nigricans and L. nigricans var.
A chemistry professor in Florida has just found a way to trigger the process of photosynthesis in a synthetic material, turning greenhouse gases into clean air and producing energy all at the same time. The process has great potential for creating a technology that could significantly reduce greenhouse ...

The team believes its work has helped solve many problems associated with the implementation of an artificial photosynthesis system and represents a major step ...
New research conducted on a fossil of the Bangiomorpha Pubescens has given an interesting fact about the photosynthesis processes. As per the latest research photosynthesis process in plants first took place 1.25 billion years ago. The data was found during research that identified an algae fossil.
New research dates the world's oldest algae fossils to over a billion years ago. And, based on that finding, estimates that the origins of photosynthesis used by today's plants dates back 1.25 billion years. The study could resolve a long-standing mystery over the age of the fossilized algae, Bangiomorpha ...
Washington, Dec 21 (Prensa Latina) The basis of photosynthesis in the current plants originated 1.25 billion years ago, according to a study with the world''s oldest algae ... His team also determined that the chloroplast (structure in plant cells where photosynthesis occurs) was created when a eukaryote swallowed a simple ...
Blue Orange Games has had quite a year, with Kingdomino winning the 2017 Spiel des Jahres award for the family game of the year, its sequel Queendomino appearing this fall, and the release of photosynthesis, my number three game of 2017 and one of the most visually arresting new titles this year.
scientists have also established that the chloroplast, the structure in plant cells that is the site of photosynthesis, was created when a eukaryote long ago engulfed a simple bacterium that was photosynthetic. The eukaryote then managed to pass that DNA along to its descendants, including the plants and ...
"The so-called 'faint young Sun paradox' has long been a topic of debate because its resolution bears important ramifications for the basic factors structuring climate regulation and the long-term habitability of Earth and Earth-like exoplanets." So begins Chris Reinhard's new paper in Nature. Reinhard is a ...

The complex and intertwined relationship of photosynthesis and respiration are part of what is known as the "carbon cycle", which is what allows carbon molecules to be recycled and work their way through the entire biosphere. Carbon is released into the atmosphere by respiration from animals in the form ...
Mimicking natural photosynthetic structures, researchers have built synthetic circuits that can be used for super-efficient, light-harvesting systems. A key mechanism for all life, whether directly or indirectly, is photosynthesis. This refers to the process of harvesting, converting, and using the energy of sunlight.
They have published an article, "High-temperature tolerance of photosynthesis can be linked to local electrical responses in leaves of pea," in Frontiers in physiology, as part of a separate research topic focused on the role of intercellular electric signals in the adaptation and communication of plants.
The samples, found on Canada's Baffin Island, also reveal roughly when plants had the components necessary for photosynthesis, a new study finds. The finding reveals that Bangiomorpha pubescens, the oldest known algae on Earth, is more than 1 billion years old. Working backward, the researchers ...
scientists aim to boost photosynthesis to meet the increasing global demand for food by engineering its key enzyme Rubisco. Now, researchers at the Max Planck Institute of Biochemistry have succeeded in producing functional plant Rubisco in a bacterium. This allows genetic engineering of the enzyme.
The imaging system detects fluorescence emitted from chlorophyll, a pigment that gives plants their green color and is essential for absorbing the sunlight plants use to create energy through photosynthesis. Monitoring chlorophyll and how photosynthesis is performed in a plant provides insight into the ...
