The Water In The Sky


We all learned in elementary school science class that trees play a very important role in the water cycle.They are vital to the entire process of getting water from the below ground to the atmosphere.Trees pull water from the ground and release it into the atmosphere as vapor through pores in their leaves in a process called transpiration, which can drive temperatures and rainfall across the globe.Before we get ahead of ourselves with this one let's start from the ground. Most of the Earth's water is held just below the ground and this is where the trees obtain the water through their root tips using the process of osmosis. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Thus begins the process by getting the water out of the ground and into the root and from there it begins its journey from the roots to the canopy. The water is pushed through the forces of cohesion and adhesion up to the the canopy. After the water has made its way up the tree it begins to to enter the meyspelloll cells of the leaf start the process of transpiration or in other words the return of water to the atmosphere in gas form. This in turn begins the water cycle over because the gas will rise until it condenses and will fall as rain and become groundwater once more. Trees and plants are very important to this cycle because without them the exchanging of h2o liquid into h2o gas would be very difficult. I hope to have given you more insight on the usefulness and necessity of trees even in our modern world.
