Kaplan and Hagemann (1991) BioScience Cell vs. Organismal Theory: Plant development Animal development 1) Plasmodesmata, symplasm 2) Phragmoplasts 3) Cell lineage patterns 4) Coenocytic female gametophyte Conclusion: there is as much evidence to view morphologically complex plants as coenocytes as there is to consider them multicellular (at least in the same sense as animals)
