Speaking of CAM plants, does anyone have an activity for demonstrating
some aspect of this pathway or distinguishing it from C4, in a way that
is suitable for high school students? (14C tracers, for example, are
out.)
I thought, for example, that it might be possible to titrate, or just
compare the pH of crude leaf extract at (simulated) dawn and dusk to get
at the idea of a diurnal cycle of C4 acid accumulation.
Many thanks for any ideas.
