The experiments in this
program use a radioactive isotope of carbon (14C) to demonstrate some of the
techniques for studying photosynthetic metabolism and the translocation of
the newly synthesized carbohydrate from the chloroplast to the various parts
of the plant where it is utilized in growth and respiration. There are two
main experiments in the program, both using the pea plant. The first is an
investigation of photosynthetic metabolism in which each of three leaves is
supplied with 14CO2 for one minute but left in the presence of light for
varying amounts of time. Using 14C-labelled reference sugars, the principal
photosynthetic products are identified chromatographically. The second
experiment is an investigation of the pattern of distribution of
14C-labelled assimilate within the plant. (15 minutes)
