Abstract

The life in the earth depends on the derived energy of the sun. The photosynthesis is the only process of biological importance that can pick this energy. The term “photosynthesis” means “synthesis that uses light” literally. The photosynthetic organisms use solar energy to synthesize organic combinations that cannot be formed without the contribution of energy. Energy stored in these molecules can be used later as source of energy to cellular processes in the plant and it can serve as resource of energy for all the life forms. It is, therefore surprising that the light can also be harmful for the photosynthesis. Evidences that the light excess can affect the vegetable growth exist and lead to the reduction of the productivity. Now that str...
