It’s not about crushing hurricanes that bring tsunami death or formidable volcanic eruptions. We will talk about which fragile and weak for life show us fragile and weak on kind of creation, making one wonder at greatness and power nature.
Plants – so familiar to us, familiar, like sun, water and air, and at the same time mysterious and almost incomprehensible, – able to develop and survive in the most difficult conditions.
The internal pressure in the cells of plants and bacteria is very high, biologists themselves call it turgor. This is hydrostatic pressure. is the result of osmotic injection of water. Thanks plants are “upright” in the vertical position, and their sprouts easily pierce not only the soil, but also asphalt.
At first, the seeds absorb water intensely and swell intensely, sprouting begins. Due to the huge intracellular seedlings overcome pressure as the thickness of the earth, and others barriers. Special devices help them, for example, bean sprouts – doubled end of the stem. Corn seedlings “use”, as with an awl, tightly folded leaves; castor stalk twists in a kind of loop and without difficulty lifts a layer of earth lying on top.
Interesting that the swelling pea seeds anatomical scientists use to separate the bones of the human skulls connected by a unique durable notched seam – for this very great force must be applied. This vegetable fantastic effect beautifully described in his documentary the story “Black Sea” by Soviet writer K. Paustovsky, who I personally watched the steamer “Dnepr”, sitting on the stones and getting a light hole, after some time was torn in two by an unknown by force, although at that time not even a slight disturbance at sea was observed. But soon everything became clear: there was peas in the holds of the ship, which got wet, swollen and just tore the iron sides of the ship, like paper, easily bent the septum and even pulled out frames.
In most plant species, internal pressure during growth is 5 to 10 atmospheres. Well-known champignons punch asphalt and concrete pavement and road surfaces, concrete floors of warehouses and garages, and their desert brethren – solid, high-strength crust of takyrs.
There are mushrooms whose hyphae can drill thin plates of gold and marble, and this penetration is purely mechanical, although very similar, for example, to a fabulous one. In general, turgor pressure in mushrooms during growth is very increases, which makes the fruit body fantastic elasticity. It equals the tire pressure of a 10-ton dump truck. Amazing, isn’t it ?!
