The mutant is a giant because its cells are , the facts that, in the cortex, the number of cell-layers isfewer in the giant than in the normal plant, and that the rate ofgrowth of the plant as a whole is slower in the former than in thelatter, suggest that cell gigantism may be due to a reduction in thenormal rate of cell-division. Examination of Figs. 2—o, shows that the cells of the giant arelarger than those of the normal form in ail thr
