It often happens that the simplest things require a complex explanation. A children's question about why green grass puts many adults, if not at a dead end, then in a very difficult position. Despite the fact that this topic is from the school curriculum, not everyone will be able to remember such words as photosynthesis or chlorophyll, not to mention the processes that are associated with them.
The answer to the question of why the grass is green lies in the plane of science. First of all, it is necessary to understand the process of formation of light perception in humans. The shades that our eyes see do not depend on the color scheme, but on its reflection under direct sunlight. This explanation is closely related to one of the main possible answers. The grass contains a special substance - chlorophyll, which in Greek means "green leaf".
Chlorophyll absorbs the entire spectrum of colors except one. It is easy to guess that this is the color of the summer lawn.
There is a second answer to the question of why the grass is green. It is he who is most often voiced in school textbooks and is closest to the truth. It is again based on the content of chlorophyll in the grass. Such a substance not only determines the use of carbon dioxide and the production of oxygen, which is so necessary for human life, but also is a special pigment responsible for the green color of the grass.
Scientists have proven that the components of chlorophyll are really green. Their color is associated with the content of magnesium, which is responsible for creating this natural shade. Plants contain many other colored pigments, however, in much smaller quantities. Thanks to them, green grass can sometimes take on a wide variety of shades.
To use chlorophyll in everyday matters, science today is not yet within its power. Its components cannot be stored and almost immediately change their pleasant tone to an unsightly dirty color. True, now there are many artificial dyes based on this useful natural material.
Thus, chlorophyll not only brings beauty to the outside world and helps us answer the classic question of why the grass is green, but it is also a very important component. Its main purpose is to produce much-needed oxygen - the basis for the life of all mankind.
This process is called photosynthesis and is carried out by absolutely all representatives of the flora on planet Earth. Briefly describing its main stages, we get the following picture: the absorbed carbon dioxide decomposes under the influence of chemical reactions, the transfer of electrons from hydrogen and water to it occurs, resulting in the formation of carbohydrates and oxygen evolution.
In addition, in the process of photosynthesis in the grass and foliage, many useful nutrients are formed, such as sugar, starch, protein.
The greener the grass, the more chlorophyll in it, and therefore the higher the benefits that it can bring to the planet.
