 Title    Interactions between Photosynthetic Pigments Bound to Lipid and Protein Particles. Spectroscopic Properties  
 Abstract    The spectroscopic (visible) properties of pigment-bearing lipid and protein particles extract­ ed from milk show that: 1) chlorophylls a and b bound to separate particles can form aggregates provided their relative concentration is high enough. Neither pheophytin a nor ^-carotene, in the same conditions, form observable aggregates. 2) Chlorophylls a and b can co-aggregate when they are bound to the same particles. Pheophytin a as well as /8-carotene seem to prevent the aggregation of chlorophyll a. p-carotene has no effect on the aggregation of chlorophyll b.

 Title    Regulation of Light Energy Distribution between Photosynthetic Pigment Systems; a Possible Role of Leaf Anatomy  
 Abstract    The complex anatomical structure of an intact leaf results in a distribution o f photosyn-thetically active energy between photosynthetic pigm ents which is different from that observed in isolated chloroplasts. The variance is due mainly to scattering at the gas-liquid interface between cells and intercellular space which tends to increase light absorption by the long wavelength absorbing pigments through secondary fluorescence. Evidence is given in support of an active use of this feature by the higher plant to regulate energy flow at the photophysical level of light absorption.
