registered in the obtained coenobia (Figs. 3–21—3–23), which represent the
number of cells in one generation. These results do not conform to the basic
rule of the proposition about synchronous division requiring rate frequency of
two (2ⁿ). The differences between synchronous and asynchronous nuclear
and cell division is shown in Figure 3–24.

Figure 3–18. Nuclei in cells of Scenedesmus acutus stained with thionine. x 1600 (Nicolov, 1982). a — two daughter cells (autospores), part of a cell coenobium; b — cell with one nucleus; c — cell with one dividing nucleus; d — cell with two nuclei; e — cell with two dividing nuclei; f — cell with three nuclei; g — cell with four nuclei; h — cell with five nuclei; i — cell with six nuclei; j — cell with seven nuclei; k — cell with eight nuclei; l — cell with sixteen nuclei; m — compact 4-cell coenobium; n — 4-cell coenobium in the course of releasing the daughter cells; o — compact 8-cell coenobium; p — cells treated with DNase, at that no nuclear structures are observed.
