Abstract
IN previous papers1,2, it has been established that when radish or carrot root slices were suspended in sucrose solution, the latter was always inverted in the medium before its absorption by the tissue slices, and the inversion was always faster than the uptake, hence the accumulation of invert sugar in the culture medium. Gawadi3 and Burström4 showed that sucrose inversion takes place by means of invertase centres attached to the outer cytoplasmic surfaces of cells of the slices. Saïd1 found that when slices of varied thicknesses were suspended in sucrose solution, the rate of inversion in the medium was directly proportional to the number of exposed surfaces per mass of tissue slices.
