Figure 4.

Yield values (PAM measurements) of Costasiella cf. kuroshimae compared to Plakobranchus ocellatus. Y is the yield value of chloroplasts' photosynthesis that has been measured every day after capture of animal. Y is plotted against the days of starvation. Trendlines are calculated in Excel. In every figure the species with the longest measured ability of chloroplasts' function, Plakobranchus ocellatus, is shown as reference. Black trendline indicates no functional retention. Trendlines of species with long-term retention are green. Standard deviation and mean values are given.
