The Three‐dimensional Shape of Interphase Cells Within the Apical Meristem of Anacharis Densa,

Growth and Organized Development of Cultured Cells. III. Interpretations of the Growth from Free Cell to Carrot Plant

“…These views, traceable to Lord Kelvin (d. Thompson, 1952), have also received attention from Lewis (1923) and recently from Matzke andDuffy (1955, 1956). -Proceeding from somewhat different premises, other concepts have been developed.…”

GROWTH AND ORGANIZED DEVELOPMENT OF CULTURED CELLS. III. Interpretations of the Growth from Free Cell to Carrot Plan

“…The efficiency by which space may be partitioned by equal and regular units leads to the emphasis upon the now familiar ortho-tetrakaidecahedra as the favored cell shape to fill space economically. These views, traceable to Lord Kelvin (d. Thompson, 1952), have also received attention from Lewis (1923) and recently from Matzke andDuffy (1955, 1956). Again, with special reference to embryos, Glaser (1938) has traced the number of cells, which are necessary in successive layers around a 14--sided initiating cell, so that it might grow outwardly in three directions when unfettered by lack of nutrients or by other restrictions.…”
