Webbspecialized cells of the phloem form a continuous network running throughout the plant. The most widely accepted mechanism for phloem transport is the osmotic pressure-driven mass ﬂow as proposed by Münch in the 1920s (Münch 1930).According to Münch, sugar produced in the leaves generates an osmotic pressure which drives a ﬂow of Webb10 jan. 2024 · The veins in a leaf represent the vascular structure of the organ, extending into the leaf via the petiole and providing transportation of water and nutrients between leaf and stem, and play a crucial role in the maintenance of leaf water status and photosynthetic capacity.

"Webb2) Phloem lipids could be transported as building blocks or energy carriers. This is unlikely since most plant tissues are capable of lipid biosynthesis and thus, the need for lipids as precursors does not exist [10]. On the other hand, the phloem composition changes during leaf senescence from sucrose to amino acids as predominant molecules [11]. " - Phloem networks in leaves
