Thursday March 1, 2001
1. Turn in plant technology research papers, journals, & lab work.
2. Light-dependent & light-independent reactions of photosynthesis.
3. Computer simulation of non-cyclic photophosphorylation
a. Observe program & list what occurs during non-cyclic photophosphorylation.
b. In scientifically organized fashion, use the program to determine which
wavelength/s and light intensities produce the greatest amount of ATP (and
thus allow photosynthesis to happen the fastest).
