Botany - Transport in Plants Question with Solution | TestHub

Root pressure is a force that helps to push fluids upward into the xylem. Root pressure is most significant in monocotyledons. Root pressure operates generally up to 2-3 m in height. Root pressure is retarded or absent under starvation condition and drought condition. Root pressure is absent in rapidly transpiring plants, conifers and plant growing in cold soils. Root pressure decreases as day advances and reaches maximum during early morning of spring & rainy season.
