Fact: The leaves of the plants produce oxygen and carbon dioxide. Question: Where goes the nitrogen? There is almost 80% of it in the atmosphere. It is known that for their life-sustaining activity plants do not get nitrogen from the atmosphere through leaves – it is to be applied to the soil to plant roots.
The theory of photosynthesis holds: “Plants eat and breathe air and release oxygen and carbon dioxide.”
But where is the nitrogen?
Why leaves do not absorb nitrogen when there is 80% of it in the air and it needs to be incorporated into the soil to the roots, but supposedly absorb carbon dioxide which only 0.03% in the air?
Why then, the plants do not absorb water, which in tropical and subtropical air and apartments is up to 5%, with their leaves?
What I mean is that nature really does very unwisely.
Why do people believe in the existence of the air nutrition and plant respiration using leaves at quite obvious absurdity of this doctrine?
It is much easier to come to the plant and look at it!
Plants do not breathe!! And it is written in all textbooks that plants do not have respiratory organs!
Plants and animals represent hydraulic systems under constant internal pressure which is greater than atmospheric pressure. The heart creates this pressure for animals and delivery vessels for plants, which are placed throughout the plant from the roots to the leaves. These are linear “pumps”, people do not know anything about them and about their construction. For example, textbooks refer only to the root pressure while a branch or even a separate leaf can autonomously maintain its internal pressure and pump fluid. Capillary effect has nothing to do with it, because it does not create pressure.
Internal pressure provides the form of any organism and is the most powerful protective device against the disease attacks of the external environment (passive protection) – in this case nothing automatically gets inside the organism there, where it shouldn’t get.
Immunity (active, “empowered” protection) goes second. (Third, if you consider the priority of contact with the nature. The skin, the fell, the peel are the first to meet the “attacks” of the environment.)
If food or air should get into the organism, there must be special organs of nutrition and respiration, because the products have to be pushed and the air has to be breathed, breaking the internal pressure of the body.
Then everything nutritional must be consumed and everything unnecessary must be removed.
In addition, the organism must have the immune defense against pathogenic attacks from food and air, and must also have a self-cleaning organs protecting it from dust and dirt entering with food and air. And many other things.
Plants have no respiratory organs and therefore plant respiration is not practically possible. It is structurally impossible. The leaves do not even have holes. Stomata are one-way valves for exhausting gases from the leaves into the atmosphere.
Is it really so difficult to have a look at it through the microscope?!
It is necessary to study living leaves, but not culled from a normal plant, without cutting, without damaging the leaf!
Studying “corpses” – culled leaves, does not entitle the researcher to draw conclusions about their intravital functioning, their role in the life of the plant, on the physiology of plants.
The peel of the leaves is transparent. The inside part of the leaf also permits light through well.
Take a plant with the most delicate and young leaves, adjust the back lighting and go on.
It is interesting!
The answer to the nitrogen mystery is simple – nothing comes inside the leaf through the stomata, including nitrogen. There is no particular problem for a plant to obtain nitrogen compounds along with the water from the soil – they are still dissolved in the water. And if you open the stomata to pass inside the leaf, a lot of insolvable problems immediately appears.
You shouldn’t take the nature as a fool. For supplying water into the plant, the nature acts like a real engineer: on the tips of the roots the plant creates a decent vacuum and sucks up the water. And then it creates the pressure in the roots which spreads through the whole plant.
That is, in case of a real need of the air supply through the stomata, there would have been necessarily discharge in the leaves.
When reading the modern biology textbooks, and textbooks in other sciences, a strong belief that they were written by Neanderthals at a time when there were no mechanisms, machines and computers arises. There was no civilization and a pioneer biologist did not know that his car would not go if the fuel pump does not create gasoline pressure. And there was no notion of what pressure or vacuum is.
But now absolutely everyone drives, opens the taps in the sink and bath, and so on and so on … And not only biologists, physicists, chemists, but also the deputies, and the ministers, and the presidents.
How can you not see the nonsense in the textbooks??!!
Shame on you!!!
