WebThe Pressure flow hypothesis is defined as the mechanism of translocation of the food through the phloem starting from the source to the sink. It is the development of pressure between the ‘source’ (leaves) and ‘sink’ (shoot and roots), which aids the transport of contents of phloem forward and downward via the sieve tubes. WebJan 3, 2024 · On the other hand, Yang et al. investigated the flow state’s changing mechanism in the impeller and guide vanes of a vertical axial-flow pump under different flow conditions. They found that, as the flow increased, the flow streamline distortion zone size on the impeller blade’s surface gradually decreased from 0.8Q BEP towards 1.2Q … WebExplain the pressure flow model for sugar translocation in phloem tissue; Describe the roles of proton pumps, co-transporters, and facilitated diffusion in the pressure flow model ...
