Plants have their tricks to suck water from the ground and raise it against gravity to tens of meters, as in trees. The suction is carried out by an osmosis process: as the roots are saltier than the earth , the water passes inside them to equalize the concentration of salt inside and outside. In addition, the root is covered with hairs that increase the surface of contact with the liquid. Perspiration is an additional aid. In vegetables, water circulates through a system of interconnected cells. When droplets evaporate through the stomata of the leaves, the pressure on these cells is reduced, thus attracting water from their neighbors . The disturbance spreads throughout the circuit and causes an internal negative pressure that reaches the roots and pulls the water molecules around them.
How do the roots absorb water?
