The in vivo absorption spectra in absolute units of semi-integral attenuance, pEt, of a brown layer (curve A) of 4 mm thick, a green layer (curve B) of 2 mm thick, a double layer (curve C) composed of the brown and the intermediate white layers (13 mm in total thick- ness) and a triple layer (curve D) composed of the brown and the intermediate layers and one half (1 mm) in thickness of the green layer. the double layer is shown by curve C in Figure 3, which indicates practically no change of attenuance below 678 m/x. This implies that the white light transmitted through the ridges predominates in intensity over the brown light transmitted through the algal part. The attenuance values read between 400 and 678 m/x ranged from to which corresponds to in transmittance. The sun light intensity on the earth may be about 100,000 lux on a sunny day in the tropical area which is roughly 500,000 erg/cm2 sec in terms of the energy available for photosynthesis below 700 m/x. The above attenuance values, therefore, indicate that the light falling on the upper surface of the green layer is 100-150 lux or 500-750 erg/cm2 sec as the energy available for photosynthesis.
