One of Hostinâs colleagues, Regina M. Jansen, a senior trial attorney at the U.S. Department of Justice, sums up Hostinâs universal appeal: âAs a leading attorney, Sunny is a brilliant woman. Her talents also include incredible emotional intelligence.
  Chloroplasts are the organelle in plant cells that produce sugar and oxygen from carbon dioxide and water through photosynthesis.
However, not all organisms that use light as a source of energy carry out photosynthesis, since photoheterotrophs use organic compounds, rather than carbon dioxide, as a source of carbon. In plants, algae and cyanobacteria, photosynthesis releases oxygen.This is called oxygenic photosynthesis.arbon dioxide is converted into sugars in a process called carbon fixation. Carbon fixation is an endothermic redox reaction, so photosynthesis needs to supply both a source of energy to drive this process, and the electrons needed to convert carbon dioxide into a carbohydrate.
