Square planar complexes can exhibit both geometric and optical isomerism.
Water Potential
Free energy of water; the water potential of pure water is zero and that of solutions is a negative value. Differences in water potential are used to predict the direction of water movement (always from a region of less negative water potential to a region of more negative water potential).
Functional Secondary Xylem
The mature, functional part of xylem that contributes to water and mineral conduction in plants, as well as structural support.
Dissolved Minerals
Dissolved minerals are inorganic substances found in water that are dissolved from natural geological sources, and are essential for various biological and ecological processes.
