A Cell Shape Study of Three Mosses, Bryum roseum, Catharinea undulata, Mnium cuspidatum, and of Ulva lactuca
Abstract
The study of shapes of cells had its beginning in 1665 when Robert Hooke observed cork cells and compared their shape to the cells in a honeycomb. Contemporary with Hooke were Nehemiah Grew and Marcello Malpighi, both of whom were plant anatomists interested in the study of tissues. Johann J. Moldenhawer was the first to note that each cell had a cell wall of its own. With the description of protoplasm by Hugo von Mohl, the discovery of the nucleus by Robert Brown, and the formulation of the cell theory by Schleiden and Schwann, interest became centered on the contents of the cell. Its part as a structural and functional unit was recognized. The shape of the cell did not seem to be of great importance. In recent years the possibility that the shape of cells may have pathological application has been suggested, and interest in the form of cells has been revived.
