. The uptake of triphenyltin chloride by Enteromorpha intestinalis and Ulothrix pseudoflacca zoospores and vegetative tissue was examined under various conditions affecting the metabolic state of the chloroplast. A synthesis for [ 113 Sn]‐triphenyltin chloride is presented. Results indicate that uptake of [ 113 Sn]‐triphenyltin chloride by vegetative tissue (and probably zoospores) is a passive process. Differences in the uptake of [ 113 Sn]‐triphenyltin chloride by zoospores of the two algae, in the dark and light, and by vegetative tissue of the two algae in the light, cannot be explained readily on the basis of surface area available for adsorption. Uptake studies suggest that differences in response to triphenyltin chloride exist between vegetative tissue and zoospores. Treatments which depress chloroplast membrane energization in vegetative tissue, e.g. lack of light, the presence of the uncoupler carbonyl cyanide m‐chlorophenyl hydrazone (CCP) or of DCMU prevent the exchange of triphenyltin chloride in pulse‐chase experiments.
