Two main theories are proposed (1) Root pressure theory and (2) Transpiration pull theory.The loss of water from the plant in the form of vapour is known as transpiration There are three main kinds of transpiration (1) Cuticular (2) Lenticelar and (3) Stomatal. Here students can get class & chapter wise Class 11 NCERT notes, which is very helpful to understand the subject and its chapter in a good manner. Organic and mineral nutrients undergo multidirectional transport. C Bose? Transport in plants Chapter 5 Plant transport systems Plant cells, like animal cells, need a regular supply of oxygen and nutrients. R : At night and early morning evaporation is very low. Like this chapter so far? R : The gravitational pull is resposible for conversion of potential energy of water in the form of energy which can do work. This pressure is called turgor pressure and the swollen condition of a cell is called cell’s turgidity. We also cover the factors that affect the rate of transpiration: light intensity, temperature, humidity and air flow. Learn from our updated notes now. We also cover the factors that affect the rate of transpiration: light intensity, temperature, humidity and air flow. Please take 5 seconds to Share. These, d) Do not show any specificity in opening and closing, of water by the root system is the result of, a) Forces created in the cells of the root, b) Increased respiratory activity in root cells, d) Tension on the cell sap due to transpiration. It is designated by the greek later “Psi” - symbol is Ψ The osmosis can be difined as - “When two solutions of unequal concentrations are seperated by a semi permiable membrane the solvent (water) diffuses from dilute solution to concentrated solution.” This process will continue till the concentration of solutions becomes the equal. Transport in plants Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. water moves out of the cell and membrane shrinks away from its cell wall.
