WebSummary. Water storage dynamics and flow facilitate the four basic soil forming processes: translocations, transformations, additions and losses of soil constituents in a soil profile. … Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata (… WebOct 12, 2024 · Water moves from the roots to the leaves through a series of interconnected “pipes” known as xylem. As water evaporates from the leaves through small openings on the leaf surface called stomata, a suction force is produced by the vascular system as the plant continually pulls water from the roots through the xylem, creating tension. derek lucht photography
