The authors demonstrate the presence of putative junctional pores by electron microscopy and other ultrastructural data that would appear to support polysaccharide secretion as the driving force for motility in this organism.
Results section headings and figure captions should be phrased as conclusions, supported by the data presented, when appropriate (can be a minor change, for example 3.2 could be titled, “Phormidium colonies form divergent structures,” or larger, for example 3.5 could be titled, “Individual filaments undergo directional reversals, with maximum velocity immediately following a reversal.”
