Three-Dimensional Cell Shape in the Carpel Vesicles of Citrus Grandis

Developmental and Comparative Cell Shape Changes in Leaf Midribs and Floats of Utricularia inflata

“…The average number of contacts (12.34) found for the undifferentiated internal cells of the midrib does not agree with the results obtained for comparable cells by Lewis (1923Lewis ( ,1925Lewis ( ,1933, Marvin (1939b, 1944), Higginbotham (1942, Dodd (1944), andHulbary (1944), all of whom obtained averages very close to 14. However, the cells of Utricularia inflata used were in contact with larger epidermal cells ( fig.…”

Epicuticular Wax on the Juice Sacs of Citrus Fruits: A Possible Adhesive in the Fruit Segments

“…Schneider (1968) referring to the work of Dodd (1944) and Davis (1932) proposed that "oil droplets" or "deposits of oil" may occur in the central region of the juice sacs. In the present work, using TEM, lipids were found not only on the outer surface of the juice sacs as waxy layers, but in other regions of the juice sac tissue of oranges and grapefruits.…”

The Three‐dimensional Shape of Plant Cells and Its Relationship to Pattern of Tissue Growth

“…His study gave parallel results to the geometric proof of Lord Kelvin (1887) that a regular tetrakaidecahedron (fourteen facets of six squares and eight regular hexagons) gave the most stable configuration with minimal partitioning of space. Other workers supported Lewis' ' results in a number of plant tissues although the regular tetrakaidecahedron occurred at a low {c. 1%) frequency (Higgenbotham, 1942;Dodd, 1944;Marvin, 1939Marvin, , 1944Duffy, 1951;Matzke and Duffy, 1956). Despite the extensive literature on the subject of cell shape a decided ambiguity remains about the cause of the observed shapes as to whether it is biological or physical.…”
