- ... Beginning with light microscopy studies in the late 19th century, the placental “nutritive tissue” in carnivorous plants of Utricularia spp. has been well described by several authors. Based on observations of direct contact between the embryo sac and the “nutritive tissue” and the lack of vascularization of the ovule, it has been suggested that this nutritive tissue plays a key role in the nutrit ...

- ... Plasmodesmata (Pd) are trans-wall membrane channels that permit cell-to-cell transport of metabolites and other small molecules, proteins, RNAs, and signaling molecules. The transport of cytoplasmic soluble macromolecules is a function of the electrochemical gradient between adjacent cells, the number of Pd per interface between adjacent cells, Stokes radius (RS), area of the cytoplasmic annulus, ...
