title: The question of chlorophyll-formation in plant tumors.
abstract: The formation of chlorophyll and the distribution of the chloroplasts in Bryophyllum tumor tissue has been studied under various conditions of illumination. The results are discussed under the assumption that a relation exists between chlorophyll biogenesis and the occurrence of differentiation processes.
