Photosynthesis At 1000 ppm CO in measuring air, both the C3 and C4 plants had similar leaf photosynthetic rates around 60 μmol CO·m·s indicating the suppression of photorespiration in C3 plants. There are three main factors affecting photosynthesis and several corollary factors. The three main are: Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of
Australian Stem Cell Centre Australian Stem Cell Centre The Australian Stem Cell Centre is an Australian medical research and development centre which focuses on regenerative medicine through the use of stem cells. Founded in 2003, the Centre is the National Biotechnology Centre of Excellence and has received over $100 million in funding in recent years. It is Australia's premier stem cell research organisation. In June 2008, the Centre announced that it had begun working on induced pluripotent (iPS) cells (human embryonic stem cells, artificially created without human eggs or embryos). This was the first time in Australia that such research had been carried out,
