Morphology and Physiology of Plant Tumors

  • Armin C. Braun
  • Tom Stonier
Part of the Protoplasmatologia book series (PROTOPLASMATOL., volume 10 / 5a)


The tumor problem is basically a problem of growth. It is, moreover. a problem of the uncontrolled growth of altered cells by more or less random division. Rate of growth does not in itself characterize the tumor cell since certain normal cell types may grow and divide at considerably faster rates than do most tumor cells. The tumor cell need not, however, be lacking the capacity to differentiate and functionate. Certain malignant teratomata may retain these properties to a striking degree. The one biological characteristic that distinguishes the tumor cell from the normal cell is its capacity for the uncontrolled or autonomous growth within an organism. Without this there would be no tumors.
