Figure 3.7 shows P vs. E curves for low- and high-light acclimated Skeletonema
costatum. Interpretation of the curve depends on the variable to which photosynthesis
is normalized. When photosynthesis is normalized to Chl-a (Fig. 3.7a), low- and high-
light-acclimated cells show similar rates of photosynthesis at low light intensities, but
