Dr. Punnett's laboratory focusses on oxygenic photosynthesis and has yielded evidence that there is a control mechanism affecting the biophysical aspects of the photochemical mechanisms, chloroplast fine structure, and probably the nature of the CO2 fixation pathway. The experimental technique used is photoacoustic spectroscopy.
Quantitative analysis yields photosynthetic rates and relative quantum yields.
Dr. Punnett is analyzing the control mechanism which allows the plant to compensate for rapid changes in its environment. Parallel studies are being conducted with the green algae Chlamydomonas. Progress in Photosynthesis Research II, ed.
