[Uptake of zinc by synchronous cells of Chlorella fusca].
The uptake of labelled zinc into the interior of synchronous Chlorella fusca was measured at 30 degrees C in minimal and optimal conditions (dark/nitrogen or light/air, respectively). No saturation with Zn was reached during 10 hours. Uptake strongly depended on the stage of the cells during the development cycle. The rates of uptake per unit cell number, per unit cell volume and also per unit cell surface, reach maxima be forecell division, and thereafter strongly decrease. Clearly the transport system is built up during cell growth. The similarity of the dependence of the rates of uptake in minimal and optimal conditions on the stage of development suggests identity of the transport systems.
