The development of the one-celled condition in Funaria (Musci) stomata was investigated using light and electron microscopy. The guard cell parent cell is unusual in that it undergoes karyokinesis but incomplete cytokinesis. The septal wall, and the cell plate from which it forms, have incurved edges in contact with the polar cytoplasm.
No evidence was found to support Haberlandt’s claim that the stomate is initially two celled but undergoes wall resorption. Preprophase microtubule bands appear to be present in nonstomatal epidermal cells with normal cytokinesis, but the possibility is raised that they are absent in guard cell parent cells.
