There have been centrists in both sides of politics, who serve alongside the various factions within the Liberal and Labor parties. In addition, there are a number of smaller groups that have formed in response to the bipartisan system who uphold centrist ideals.
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
Most plants incorporate carbon dioxide into sugars by means of a cycle of reactions called the :, Calvin cycle. Flattened sacs of internal membranes associated with photosynthesis are called :, thylakoids . For photosynthesis in green plants, the electron donor for the light dependent reaction is :, water . In the light-independent reactions of photosynthesis, CO2 is added to a five-carbon molecule known as :, RuBP . Jan Baptista van Helmont did an important experiment related to photosynthesis.
