Abstract

SUMMARY: In phototrophic chlorophyll content/organism is modulated both by varied amounts of chlorophyll/chloroplast and by number of chloroplasts/ organism. In unlimited growth, Euglena never has less than 7 to 10 chloroplasts on the average, each containing 0.35 to 1.0 pg chlorophyll, depending on conditions and age of culture. Chloroplasts rarely contain more than 1.1 pg chlorophyll, and organismic levels greater than 10 to 12 pg are accomplished by an increased number of chloroplasts (to 60 in this study). Chloroplast replication is tightly coupled to that of the organism in log phase growth, but not in the lag and early stationary periods of growth.
