Introduction to Transport of Water and Solutes in Plants
Web1. As water diffuses from one cell to the next, an unbroken column of water is formed. Continuous diffusion of water from the root cells pushes the water upward. 2. Water is constantly lost through the leaf surface due to transpiration. This creates a pull and the water column is pulled from above. Thus, due to the combined effect of the ... WebWater potential and transpiration influence how water is transported through the xylem in plants. These processes are regulated by stomatal opening and closing. Photosynthates (mainly sucrose) move from sources to sinks through the plant’s phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem. trump\u0027s reaction to hearing
