Transpiration is the loss of water from a plant in the form of water vapor. absorbed by roots from the soil and transported as a liquid to the leaves via xylem. leaves, small pores allow water to escape as a vapor. less than 5% remains in the plant for growth.
That's where xylem and phloem come in. Zippy Xylem The xylem of a plant is the system of tubes and transport cells that circulates water and dissolved minerals. As a plant, you have roots to help you absorb water. If your leaves need water and they are 100 feet above the ground, it is time to put the xylem into action! Xylem is made of vessels that are connected end to end for the maximum speed to move water around. They also have a secondary function of support. When someone cuts an old tree down, they reveal a set of rings. Those rings are the remains of old xylem tissue, one ring for every year the tree was alive.
