WebbPhloem: Living tissue which transports food (as solutes) from the leaves around the plant, supplying respiring cells with required sugars and amino acids. Sieve tube elements are fused end to end, with perforated sieve plates separating each element, forming a long hollow structure. WebbWater 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.
