The subcellular localisation of absorbed copper in <i>Fucus</i>

Abstract

The localisation of absorbed copper in the brown seaweeds Fucus vesiculosus L. and Fucus serratus L. was studied by X‐ray microanalysis in the electron microscope. The metal was localised in the physodes of the photosynthetic and inner non‐photosyn‐thetic cells. No significant copper was found in the cell walls of these algae, which had been collected from sites which were continually polluted by run‐off from old copper mines.
