WebThe cytoplasmic bridges that form by incomplete cytokinesis are large enough (diameter range of ~0.2–10 m, see Table 1) to μ allow organelles and/or macromolecules to pass.11 This thus rep-resents a very intimate and direct type of intercellular commu-nication and complements the multitude of ways by which cells WebDec 26, 2016 · Firstly, the two plasma membranes are brought in contact and the protoplast are induced to create destabilized regions on the membrane. When two such regions of adjacent protoplasts coincide, the membrane fusion occurs and produces cytoplasmic bridges. This results in the mixing of the two cytoplasms.
