Hardly any of us, watching the outside world, thought about this fact, each green leaf on a tree or bush is amazing, in fact, spontaneous laboratory, one of the most remarkable and mysterious of all creatures on earth.The fact that this piece of almost every second until it gets light from the sun, made a great dream not only biochemists, science fiction, and as each person: there is the creation of life from non.Really, truly amazing it seems that only green plant without cutting-edge technologies and devices can create living matter.So it is no exaggeration saying that this process - photosynthesis - is a real and unique anywhere else "creative life."This begins with the creation of the work concluded in the plant sunbeam.This complex biochemical process, and is the process of photosynthesis.
We know of photosynthesis from the school curriculum and other sources.We know that the materials needed to replicate the process of photosynthesis, are extremely simple: carbon dioxide, water and solar energy.But for them to come into play various salt solutions, which are delivered to the plant roots from the soil.
All vegetation around us, all the fauna, finally, we are (the people) - it's just wonderful green food consumers.
Carnivores eat herbivores, they, in turn, the plant.So there is a process in which all live off the food that is prepared with green plants.
short, green plants - a common "breadwinners."However, this should not be limited, because we should not forget about the air we breathe.After this plants and photosynthesis taking place in them, by means of chemical transformations led to the isolation of pure oxygen.And it can be completely safe to assume that the oxygen in the air as one of its components, providing us with green plants.In fact, millions of years of plant cells that create volatile shell globe - the atmosphere, without which life is simply impossible.Indeed, with great difficulty, we can imagine that would be a Land is not whether her plants, and consequently, other living organisms and creatures that are somehow connected with them.
likely be reminded continents earth surface a desert planet, and all this would be shrouded in deadly carbon dioxide and caustic ammonia.So it would be if the world were not plants, and hence, life could not exist as such.
So what is the power that gives it all, and where its source?The source of such power - our sun.Green leaves, like solar mechanisms currently concentrated in solar energy.And then the work begins in the world, in which a ray of sunlight turns green leaf into force throughout the life around us.
So, we can say this: the sun's energy in a certain way "landed" green plants, and then began to use it to generate life on Earth itself.
So, without resorting to tochym and rather incomprehensible scientific wording may look a general characteristic of photosynthesis.
It can only happen in an undamaged sheet.This can be seen if a glass rod under slight pressure swept across the surface of the living, green sheet (ie. E. Damage the interior of the structure without any noticeable external changes) - photosynthesis immediately cease.
Many discoveries of natural science were mined very simple, uncomplicated experiments.And on the same simple tests can prove again and again the great scientific truth.
Van Helmont, Frederick Blackman, Timiryazev based their theory on the fact that green leaves on light (ie. E. When they fall sunbeam) absorb carbon dioxide from the air and release oxygen into the atmosphere.We own eyes can always sure how the reaction of photosynthesis.
To do this in a glass jar put some zelenolistnuyu twig (in winter it is possible and on indoor plants).Then make a normal breath in this jar and immediately put it in the bank lighted match.We will see that the match instantly extinguished.
Therefore, it happened because in a lot of air exhaled carbon dioxide - about four and a half percent.And this gas, as we know, does not support combustion.
to continue the experiment.Immediately close the jar with a green sprig of dense, tight stopper so that the outside air can not penetrate into it, and expose to sunlight or bright electric light.We repeat our actions to match a few hours later.In this case, we see that she dropped into a bank goes out and lights up.It becomes apparent that the air inside the cans of green branch was again suitable for burning in it.This is because carbon dioxide has become smaller and more oxygen.
That is as simple as it seems at first glance, the way and to support life.
