This study reveals a nuclear protein complex consisting of SMXL5 and OBE3 to be essential … 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.

Transport of Water and Solutes in Plants Biology II

WebThe food in the form of sucrose is transported by the vascular tissue phloem. Let us learn a bit more about phloem transport. The transportation occurs in the direction of the source to sink. Transport of organic solutes from one part of the plant to the other through phloem sieve tubes is called translocation of organic solvents.
