Das Wachstum der Zellwand in synchronerChlorella

Summary By pulse labelling, it is shown that the relative growth rate of cell wall substances in synchronousChlorella has a sharp maximum at the time of autospore formation. The dependence on time of the rate of growth of the cell wall coincides with that of the rate of increase of the free space. Moreover, the increase of the nitrogen content of the cell wall also has a maximum roughly at the same time as the growth rate.
