Photosynthesis essay 7

Photosynthesis is the process undergone by plants consisting of a series of chemical reactions that require four factors; water, carbon dioxide, radiant energy and temperature using chlorophyll molecules to trap radiant energy from the sun resulting in the making of glucose and oxygen as bi-products.

A net reaction can be written as follows, using glucose as the carbohydrate. For many years after the raw materials and end products of photosynthesis were known, it was thought that carbon and oxygen separated during the process, in such a reaction, carbon would attach to water, and oxygen would be released.

The chlorophyll bearing plants trap the free energy of sunlight as photons and transform and store it as chemical potential energy by combining CO 2 and water. The end products of photosynthesis are carbohydrates with loss of oxygen. These directly or indirectly serve as the source of energy for all living beings, except chemosynthetic bacteria.

Photosynthesis is defined as the process by which green plants manufacture their food (organic compounds) making use of carbon dioxide and water in the presence of sunlight. It is also the synthesis of carbohydrate from sunlight, water and CO2 by the green plants. It is an endergonic and anabolic process.
