Fig. 5. Cell size distribution of log phase cells. (A) Photomicrographs of wild-type (B214) and fa2-2 cells. The fa2-2 cells are larger (on average) with respect to length, width and volume. (B) Size distribution of wild-type, fa2-2 and fa2-2 rescued cells. Cell volumes were calculated from length and width measurements as described in Materials and Methods. The mean volumes were: wild type (151 µm³), fa2-2 (287 µm³) and fa2-2 rescued (152 µm³). One hundred cells from each culture were measured.
