WebOct 27, 2024 · In case of diffusion, the movement is random and is independent of each other. It occurs along concentration gradient and kinetic energy and converts solvent into solution. The imaginary potential of solute particles to diffuse from its higher concentration to lower concentration is termed as diffusion pressure (DP).

WebSugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. Sinks include areas of active growth (apical and lateral meristems, developing ...

WebThe linear-sorption exchange reaction considers that the concentration of solute sorbed to the porous medium is directly proportional to the concentration of the solute in the pore fluid, according to the relation C = KdC, (6) where IQi is the distribution coefficient, L^M'l. This reaction is assumed to be instantaneous and reversible. WebThe pressure flow hypothesis, also known as the mass flow hypothesis, is the best-supported theory to explain the movement of sap through the phloem. It was proposed by Ernst Münch, a German plant physiologist in 1930. A high concentration of organic substances, particularly sugar, inside cells of the phloem at a source, such as a leaf, …
