What my boys does with their water
First my kids gets all of their water from the soil and this water comes from me watering them daily.The soil provides the water and nutrients necessary for them to grow. The water is absorbed by the roots and begins the water cycle inside them. The water first encounters the Xylem, which is a bunch of dead cells. Their job is to transport the water through the plant using tension to pull the water up from the roots through the vascular tissue, to all parts of the plant. While this water is being transported through the plant, it is blocked from entering the main parts of the roots and stem by the Casparian Strip. This is a band of cell wall like material, used to block water from entering certain parts of the plant. Once the plant has used the water it will sweat it off, so to speak. This process of the plant "sweating" is known as Transpiration. Another neat thing that my boys do is called Turgor pressure. This is where they ex-spell water from their cells in order to balance out their osmotic pressure to make sure they do not burst. During this process the leaves regulate the exchange of the gases carbon dioxide and oxygen through the Stomata. The Stomata are tiny pores on the leaves, stem, flowers, and roots that sweat off the water. There are specialized cells called guard cells that regulate the size of the Stomata opening in order to control how much gas is exchanged.
