Difference Between Apoplast and Symplast

Webb21 maj 2015 · Apoplast creates a main pathway called apoplastic pathway or apoplasty that helps to transport water and ions from the soil through root to xylem elements. In the plants with secondary growth, the major portion of water is transported by apoplasty in the root cortex as cortical cells are loosely packed and have low resistance to the water flow. Webbof sugar loading: apoplastic and symplastic with or without polymer trapping [8].
