Now let's compare the photosynthetic efficiency of the two different types of leaves: sun-adapted and shade-adapted. Based on the data you collected in Procedure I (100% illumination) and Procedure III (15% illumination), can you see any pattern in how efficiently sun-adapted versus shade-adapted leaves produced oxygen?
a) Sun-adapted leaves produced more oxygen in Procedure I but less in Procedure III.
b) Sun-adapted leaves produced less oxygen in Procedure I but more in Procedure III.
c) Shade-adapted leaves consistently produced more oxygen.
d) There is no discernible pattern in the data.
