Fig. 3. Incorporation of NaH¹⁴CO₃ into the trichloroacetic acid (TCA)-soluble fractions of the algal cells (A) and animal tissue (B) of A. viridis under non-photosynthesizing (black bars) and photosynthesizing (white bars) conditions, expressed as a percentage of the total radioactivity in the TCA-soluble fraction. Bars represent means ± S.E.M. of 12 and 9 replicates, respectively. Multivariate analysis of variance (MANOVA) for data expressed as d.p.m. mg^–1 protein after logarithmic transformation: Wilk's for algal cells/animal tissue, F_3,34=53.35, P<0.001; for photosynthesizing/non-photosynthesizing conditions, F_3,34=169.25, P<0.001; interaction, F_3,34=19.26, P<0.001. The full data set showed homogeneity and closely approached normality.
