Notes:
The in vivo absorption spectra of the chloroplast and eyespot of Euglena gracilis were obtained by microspectro-photometry. The average chloroplast absorption spectrum shows major peaks at 430-43S and 675-685 mμ. The fine structure details of chlorophyll à show peaks at 675, 685 and 695 mμ. The average eyespot absorption spectrum shows major absorption in the region of 460-490 mμ, and two additional peaks near 510 and around 530 mμ with lesser peaks at 430 and 630 mμ. Some of these same absorption peaks were obtained for the eyespot of E. granulata and the “hematochrome flecks.” The eyespot spectrum indicates that probably more than one ca-rotenoid is present and that a correlation exists between the eyespot absorption spectrum and the Euglena phototactic action spectra.
