Cycles Of Seed Evolution The Basics. Sunlight plays a much regretful role in our sustenance than we may expect: both last(predicate) the food we eat and all the fossil fuel we busy is a product of photosynthesis, which is the process that converts energy in fair weather to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacterium (Figure 1). The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by blue-green algae and their relatives, which are responsible for a major part of photosynthesis in oceans.
All these organisms convert CO2 (carbon dioxide) to organic material by reducing this gas to carbohydrates in a rather abstruse set of reactions. Electrons for this reduction reaction ultimately come from water, which is so converted to oxygen and protons. Energy for this process is provided by light, which is preoccupied by pigments (primarily chlorophylls and carotenoi...If you want to get a full essay, specify up it on our website: BestEssayCheap.com
