The Most Wanted Process of Photosynthesis

You know that photosynthesis is a process that must happen. Because If it loose it's process, our world won't be like this. So You also need to contribute to maintain that Most Wanted process. Most people don't know about this and they put all of us in risks by making down this photosynthesis.

Concept of Photosynthesis

Scientists believe that the earth was formed about 4.5 billion years ago and that it had a high temperature and and an atmosphere which had simple molecules such as hydrogen, nitrogen, carbon dioxide and water. As the atmosphere cooled gradually the water vapour condensed and formed the oceans. Scientists believe that amino acid and other simple molecules dissolved in this water to form the"Primitive Soup" and life originated as chemosynthetic organisms inside this primitive soup. The chemosynthetic organisms use the energy released by the oxidation of iron to produce food in the form shown below.

C02 + H20 -----------> Simple Sugars.

As time passed by, after another 12 million years the evolution of a complex molecule named chlorophyll took place. This molecule had the ability of obtaining energy from sunlight. hence the process,

6CO2 + 6H2O + ------------------> C6H12O6 + 6O2

Started. This action, which involves light energy is known as photosynthesis.

Importance of Photosynthesis

The chemosynthetic bacteria which lived for over the last 27 million years exist as unicellular organisms even today. The unicellular photosynthetic organisms evolved to be multicellular and could change into trees on land and marine plants which are hundreds of metres long. This shows the importance and the environmental suitability of photosynthesis. In addition to the food production, oxygen is released as a byproduct. This created an environment for the living organisms to have an efficient aerobic respiration. The oxygen that rose to the higher levels changed to ozone and formed a layer which protects the earth from destructive sun's rays such as ultra-violet rays. As carbon dioxide which is considered to be a green house gas is needed as raw material in photosynthesis. The atmosphere provides a friendly environment for life.

The first stage of any food chain is a green plant which is the producer. The green plants are producers because of chlorophyll. There will be no living organisms on earth if not for this process. Now you may realize that the origin of man - Who has developed the ability to control the environment is also due to photosynthesis.

Products of Photosynthesis

Carbon dioxide and water react in the presence of sunlight to produce a simple sugar named glucose while giving out oxygen as the byproduct. This process is know as photosynthesis.

Carbon Dioxide + Water +  ----------------> Glucose + Oxygen

6CO2 + 6H20 + ---------------> C6H12O6 + 6O2

How about this one? Great! Awesome! Or Nice Then just share with your friends and Comment your Idea Below. Appreciate it!

Photosyntesis, I remembered my Biology class in High School about this. Do you know about Cost of Electricity in Singapore?
