Ion Absorption by Shoot Tissue: Kinetics of Potassium and Rubidium Absorption by Corn Leaf Tissue.
The relative impermeability of the surfaces of leaves to water and mineral ions in solution is a condition upon which the life of terrestrial higher plants depends. However, for the investigator this feature imposes difficulties on attempts to make quantitative studies of the process of ion absorption by leaf tissue. The importance of this absorption process in the physiology of leaf cells has ...
متن کاملIron Absorption by Enzymically Isolated Leaf Cells'
The rate of Fe absorption by cells enzymically isolated from tobacco leaves is corre'ated with the age of the leaves from which the cells are derived4 The cells obtained from younger leaves absorb Fe more rapidly than those from older ones. Ca inhibits Fe and Mn absorption. Fe and Mn are mutually antagonitic in their absorption by leaf cells. Ca enhances the inhibition of Mn absorption by Fe, b...
متن کاملLight-enhanced potassium absorption by corn leaf tissue.
The rate of absorption of potassium by slices of corn leaf in the light was about twice the rate in the dark. When the light was turned on or off, changes in the rate of absorption took place some minutes after the change in illumination. Experiments with the antimetabolites, 2,4-dinitrophenol and cyanide, indicated that the source of energy for active accumulation of potassium by green tissue ...
متن کاملAbsorption of copper, zinc, and manganese by sugarcane leaf tissue.
The absorption of Cu(2+), Zn(2+), and Mn(2+) by leaf tissue of 4-month old sugarcane plants (Saccharum officinarum L., var. H53-263) has been investigated. After the "apparent free space" fraction was desorbed, the absorption of Cu(2+), Mn(2+), and Zn(2+) yielded a curve typical of many ion uptake processes when measured as a function of the external concentration. However, only 1 absorption me...
متن کاملIon Absorption and Retention by Chlorella pyrenoidosa
MIost of the plant ion absorption experiments in the past have been condlucted with coenocytic algae and higher plants (24). In mature cells of these organisms the vacuole occupies 80 to 90 % of the cell volume. With respect to ionic movements the cytoplasm and vacuole represent 2 distinct physical compartments (2,16). As a result, the molecular details associated with ion absorption, as well a...
