Photosynthesis

It is the process by which plants make food by which solar energy is trapped by auto tropic organism and converted into food for the rest of organisms. No other chemical process on earth can match the output by photosynthesis. It is interesting to note that only 0.2 percent of the light energy on earth is utilized by this process of photosynthesis.

Fossil fuels such as coal, petroleum, and natural gas are also product of photosynthetic organisms which lived million of years ago. Importantly it is the only natural process by which oxygen is liberated for using by other organisms.

Chemistry of Photosynthesis

Here is what hapoens during the process of Photosynthesis

1. Light reaches the cells that contain chlorophyll.
2. The chlorophyll absorbs the light energy and changes it into chemical energy.
3. Water molecules in the cells break up. The oxygen from the water is set free.
4. The hydrogen from the water molecules combines with the carbon dioxide from the environment to form glucose a simple sugar.
5. The glucose molecule is held together by the chemical energy. In other words, the energy is trapped within the glucose molecule.

Importance of Photosynthesis

Photosynthesis is Important for the world because it provides food and oxygen, which are the most important for human beings and animals. Some of the glucose that plants produce during the process of photosynthesis is stored in fruits and roots. Thus, we get apples, potatoes, watermelons, and many more, which are used in food for human beings and animals also. The oxygen peoduced during this process is released into the atmosphere.

During the process, carbon dioxide is also consumed, which had bad effect on us. As such photosynthesis is very important for the whole world.
