Document Summary
Chapter 8: photosynthesis: photosynthesis is a process in which light energy is captured and used to synthesize glucose and other organic molecules, all aerobic organisms rely on the oxygen produced from photosynthesis for cellular respiration. In the 1650s, jan baptista van helmont transplanted the shoot of a young willow tree into a bucket of soil with a known weight, and allowed it to grow for 5 years. Today, we know that co2 also makes up a portion of the mass of plants. In the 1770s, jan ingenhousz determined that sunlight is necessary for oxygen production by plants: nicholas th odore de sassure showed that water is also necessary for oxygen production by plants. Senebier showed that co2 is also necessary for oxygen production by plants. A can be either o or s, and ch2o is the carbohydrate. In green plants the a is o and the 2a is o2.
