Phloem leaf function
Webb14 apr. 2024 · Zhao et al. treated cucumber leaves with FITC-labeled mesoporous silica nanoparticles (MSNs) (particle size 200–300 nm), and found that FITC-labeled MSNs could be absorbed by the leaves. Researchers found that polystyrene nanoplastic with size of 93.6 nm could cross the barrier on lettuce leaf and enter the phloem in plants via TEM . 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].
