Plant Physiology: Processes and Mechanisms
Root Pressure
Root pressure is maintained by water accumulation in the root tissues. This generates pressure on xylem sap, pushing it upwards. Guttation is evidence of this phenomenon, typically in tropical jungles.
Gas Exchange
Stomata
Stomata are specialized structures of the epidermis formed by two kidney-shaped cells, called guard cells, which define a space between them, the ostiole. After entering the ostiole, CO2 diffuses into the intercellular spaces of the tissue, enters the cells, and reaches
