Exercise 10

How can we be sure that the two distinctive responses to temperature shown by Atriplex lentiformis were due to acclimation and not the result of genetic differences (see fig. 5.13)

Figure 5.13 Growing the same species of shrub in cool versus hot environments altered their optimal temperature for photosynthesis. This change was a short-term physiological adjustment due to acclimation (data from Berry and BjörkmaN₁980, after Pearcy 1977).
