What is Photosynthesis/ Photosynthesis, Fiber and Materials
Transcript of What is Photosynthesis/ Photosynthesis, Fiber and Materials
It has transformed the world into the hospitable enviroment we know today liberating oxygen and consuming carbon dioxide. Fills all of our food requirements and all of our needs for fiber and building materials directly or indirectly We can learn how to increase crop yields of food, fiber, wood, fuel, and how to use our lands in a better way Men have found new ways to use solar energy.For instance, compact computers and even new medical breakthroughs Glossary The process of plants obtaining nutrients through solar energy and releasing oxygen.
Photosynthesis An oily, thick, flammable, usually dark-colored liquid that is a form of bitumen or a mixture of various hydrocarbons, occurring naturally in various parts of the world and commonly obtained by drilling Petroleum The star that is the central body of the solar system, around which the planets revolve Sun Any gass whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, and ozone Greenhouse Gases Current Events on Photosynthesis Research at the Massachusetts Institute of Technology has resulted in the development of an artificial leaf that mimics photosynthesis, which converts sunlight and water into usable energy. The device represents a new type of solar cell, which uses inexpensive materials like nickel and cobalt as catalysts. This device is about 10 times more efficient at photosynthesis. That’s equivalent to about 5.5% conversion efficiency, and there is still room for improvement. The catalysts in the solar leaf, nickel and cobalt, split water into hydrogen and oxygen, which can be used in a fuel cell to provide electricity.

The artificial leaf is an excellent example of that strategy. This, however, is a story about how science wants to improve nature in an effort to address a growing population and dwindling fossil fuel resources. According to an announcement by the National Science Foundation, $10.3 million is being awarded to scientists to support scientifically engineered improvements of the process of biological photosynthesis. The funds come from a collaboration between the NSF and the U.K. Biotechnology and Biological Sciences Research Council and are being divided amongst four transatlantic research teams which the organizations identified as the most promising candidates for managing to “overcome limitations in photosynthesis that could lead to the development of new methods for significantly increasing the yields of important crops for food production and/or sustainable bioenergy.” Anne Jones of Arizona State University leads the “Plug and Play Photosynthesis” project. The focus is on separating the capture and conversion of solar energy into fuel (a process that is carried out by a single cell) into two different organisms that would communicate with one another through electrical currents flowing between them.
Stephen Long of the University of Illinois runs “Exploiting Prokaryotic Proteins to Improve Plant Photosynthesis Efficiency” (EPP)- their focus is on a metabolic process called photorespiration which reduces the yields of plants by up to 50%. The team has identified protein structures in some blue-green algae that show promise in reducing the loss, thus increasing plant yield.
John Golbeck of Pennsylvania State University oversees Multi-Level Approaches for Generating Carbon Dioxide (MAGIC). Their project also addresses photorespiration by proposing to attach special proteins to photosynthesizing cells that will pump carbon dioxide from the atmosphere into cells.
Finally, Martin Jonikas of Stanford University runs Combining Algal and Plant Photosynthesis (CAPP). They propose to use a ball-shaped structure within the cells of green algae and move it to other plants so that they can better assimilate carbon and improve photosynthesis efficiency.

Wool production depends on photosynthetically-derived energy.
Many of our other materials needs are filled by plastics and synthetic fibers which are produced from petroleum, and are thus also photosynthetic in origin.
It is not difficult to name an economically important material or substance whose existence and usefulness is not in some way tied to photosynthesis. Glossary An organic fiber, which is obtained naturally, notably from a plant or animal.
Natural Fibers A synthetic fiber is a man-made fibers that come from chemical resources. Synthetic Fibers The process of plants obtaining nutrients through solar energy and releasing oxygen.
Photosynthesis The hard fibrous material that forms the main substance of the trunk or branches of a tree or shrub. Wood Material manufactured in thin sheets from the pulp of wood or other fibrous substances, used for writing, drawing, or printing on, or as wrapping material Paper http://www.themanutdfan.com/blog/wp-content/uploads/2010/07/manutd-kit-made-by-plastic-bottle.jpg A soccer shirt made out of old plastic bottles
