title: THE OCCURRENCE AND SIGNIFICANCE OF ENDOSYMBIOTIC CHLOROPLASTS IN THE DIGESTIVE GLANDS OF HERBIVOROUS OPISTHOBRANCHS(1).
abstract: Intact algal chloroplasts have been found in the digestive glands of 5 species of Opisthobranchia belonging to the order Saccoglossa. Preliminary studies on 3 of these confirm their endosymbiotic nature. It is suggested that the occurrence of these endosymbiotic organelles may be widespread among related species of Saccoglossa. Their independent functional existence supports the view that chloroplasts possess a system of nonchromosomal inheritance.
