Abstract

Occasional nuclei of inner onion epidermis cells were found to contain a structure which we believe to be an intranuclear vacuole. These structures appeared circular, homogenous, hyaline, sharply outlined and averaged approximately 35% of the thickness of the nucleus (assuming spherical form) but decreased the dry mass concentration through their part of the nucleus by approximately 56%. We conclude that these are elongate along the axis of the light path.
