👉 Plant fluids, often referred to as sap, are vital components of vascular plants that transport essential nutrients and water throughout the plant's system. This fluid is primarily composed of water, dissolved minerals, sugars, and various organic compounds. The movement of sap is driven by a combination of factors including transpiration (the evaporation of water from leaves), root pressure, and cohesion-tension mechanisms. Transpiration creates a negative pressure in the xylem, pulling sap upward from the roots to the leaves, while cohesion and adhesion between water molecules maintain the fluid's flow. Additionally, sugars produced in the leaves during photosynthesis are transported via sap to other parts of the plant, supporting growth and metabolic processes.
