WebADVERTISEMENTS: As with the phloem loading process, sucrose unloading also occurs through symplast via plasmodesmata or through apoplast at some point en route to sink cells. Phloem unloading is typically symplastic in growing and respiring sinks such as meristems roots, and young leaves etc. in which sucrose can be rapidly metabolized. … WebApr 21, 2024 · The key difference between symplast and vacuolar pathway is that in the symplast pathway, water does not enter into vacuoles while in the vacuolar pathway, water passes into vacuoles.. Water moves through plant cells, especially across the root, via three major pathways. They are apoplast, symplast and vacuolar pathways.In the apoplast …
