The flora is diverse and beautiful. When we think or talk about nature, come immediately to mind an abundance of lush green grass and trees are bursting with oxygen, covered with green foliage. And why are leaves green?
Green leaf - a small factory of oxygen that is essential for breathing humans and animals inhabiting the Earth. Green leaves and grass accustomed eye and evokes pleasant thoughts about the freshness and health. And so it is, in fact green leaves - alive. And, as in all living organisms, they occur chemical processes essential for life. These processes are necessary for the growth of a plant, its nutrition and respiration.
What is the chemical process takes place in a sheet, contributing to its coloring in green? This process is called "Photosynthesis" and is carried out in two stages. The first step - the absorption of light, the second phase - the use of light in a chemical reaction (reaction of carbon dioxide and water).
The absorption of light occurs with an adhesive, a pigment, entitled "chlorophyll". Light has a wide color spectrum, but not any chlorophyll absorbs light quanta, but only with a certain wavelength of light, because it affects the rate of photosynthesis.
The fastest way this process occurs in the blue-violet and red regions of the spectrum, so these colors absorbs chlorophyll. The green color of the spectrum gives a very minimal rate of the process and, therefore, is not absorbed and reflected from the sheet.
The human eye is able to distinguish colors only in sufficiently, so he sees reflected green spectrum, which is an indication that the plant photosynthesis takes place.
In the worksheet contains other pigments, but their effect is too weak and muffled impact of chlorophyll. When the world becomes smaller, for example, in the autumn, the chlorophyll disappears, and their role is paramount, and the leaves take on a different color - yellow or red.
In the second step of photosynthesis, a chemical reaction of a compound of carbon dioxide from the atmosphere (exhaled humans and animals) and water from the root system. This reaction leads to the formation of glucose and other nutrients and oxygen evolution. Substances are useful for both the plant itself and for the people and animals who use it for food.
The role of oxygen in the world is enormous: it is required for respiration and to ensure all life processes in humans and animals as well as in other chemical processes such as combustion, in which also carbon dioxide is released. Therefore, the plant is called the "lungs of the planet."
