Flow cytometry measurements for <i>Chlorella vulgaris</i> cells labeled with BODIPY 505/515.

<p>All axes are logarithmic scale. (a) Flow cytogram of BODIPY fluorescence vs. forward scatter of cells after four days culturing in replete or nitrogen-limited medium. (b) Histogram of forward scatter for cells after four days culturing in replete or nitrogen-limited medium. (c) Histogram of BODIPY fluorescence for cells after four days culturing in replete or nitrogen-limited medium. (d) Box plot of medians and interquartile ranges (25th and 75th percentiles) for BODIPY fluorescence of cells after three and four days culturing in replete or nitrogen-limited medium.
