Fig. 2. Incorporation of NaH¹⁴CO₃ into the principal chemical fractions of the algal cells (black bars) and anemone tissue (white bars) of A. viridis under photosynthesizing (A) and non-photosynthesizing (B) conditions. Bars represent means ± S.E.M. of 14 and 11 replicates, respectively. TCA, trichloroacetic acid. 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_3,40=72.34, P<0.001; for photosynthesizing/non-photosynthesizing conditions, F_3,40=103.60, P<0.001; interaction, F_3,40=20.43, P<0.001. The full data set did not conform to the assumption of normal distribution and homogeneity, but exclusion of the non-conforming data resulted in no change in significance levels.
