Behind this simple picture; There are millions of cells in each leaf are working, each cell has a highly complex mechanism of action, has the ability to reproduce, continuous and repeated endlessly.
This morning, Leaf; just change the operating system. Last night inhale oxygen and release carbon dioxide, in the morning until late afternoon carbon dioxide and emit oxygen be turned on. Soon; Leaves entire forces around the world will perform exceptional operations to ensure the food supply of the entire population of the earth through photosynthesis by chloroplasts which will pull through the operation so complicated but very quickly, starting with the absorption of sunlight by the leaves. The series of complex chemical reactions take place every second in the chloroplast.
The Photosynthesis also serves to produce oxygen, one of which the human body use to burn the glucose into energy. There is a perfect balance between oxygen consumption by humans and animals by the amount produced by plants. If the amount of oxygen is increased or decreased a few percentage points, then this earth will heat and wildfires will occur everywhere.
The sunlight with specially designed colors that enables the photosynthesis occurs only. Just the atmosphere with the right composition that allows the whole process went well. And, this perfect cycle taking place throughout the world, every fraction of a second, continuously and without blemish
