🌼The little geese flower🌼

Good morning my loves💋

I'm completely blown away.I've just discovered a small meadow with lots of daisies.Fascinated considering that flowers can push through asphalt.

Most plants can not tolerate salt water. In the presence of water, however, they suck themselves fully. Because when the salt concentration inside the cells is higher than outside, water flows in the desired direction. Until the cells are full. This increases the pressure in the plant. "This osmotic pressure can be very high: up to 15 bar." An astonishingly high value, bearing in mind that you inflate a car tire with just two bars.

Thanks to the pressure in the cells, trees and their roots can endanger the foundations of houses. And even a small dandelion, which is in juice and power, is able to push through the asphalt to the light.However, asphalt is not a very hard surface. A binder derived from petroleum holds the mixture of grit, sand and fine rock flour together. This bitumen hardens over time, the asphalt becomes brittle. If moisture penetrates into the coating, binders and the other substances can be chemically separated earlier. The asphalt swells, causing cracks.In addition, road asphalt is deformed by heat. During the day the sun heats it up, at night it cools down and pulls itself together. Even so, tiny cavities and crevices are created, in which a sprout forces itself into it. Millimeter by millimeter he grows upwards. At some point he is through.

I hope you enjoyed the little excursion into biology.Today I will enjoy the sun and the warmth in Berlin.

Wish you a wonderful day.☀️
