This positive pressure occurs in the xylem either in deciduous trees when the leaves are shed in early winter or when the plant is in a saturated or near saturated condition. Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. c) Suction pressure d) Capillarity. Please keep a pen and paper ready for rough work but keep your books away. (i) Define root pressure. ; The transpirational pull: when the plant loses water through transpiration from the leaves, water and mineral salts from the stem and roots moves, or is `pulled', upwards into the leaves. This section explains to the learners how excessive loss of water can cause plants to wilt and lose some of their structural support. The value of the atmospheric pressure on sea level is one atmosphere which is considered to be standard atmospheric pressure or normal pressure. Growing a potato in water for a science project will allow students to see the growth of a root system and experiment with how different nutrients affect the growth of the potato.
