Summary
A new type of cytoplasmic structure is described in the root tips ofAllium cepa and several other genera. They are very probable composed of insoluble phosphate salts and as such can be demonstrated at the light and electron microscope level by conversion into its lead salt. They appear to be formed by coalescence of electron dense “vesicles” which have granular phosphate deposits at their periphery.
