      Like any other biological tissue, plant tissue also exhibits optical properties like refraction, transmission,absorption, coloration, scattering and so on. Several studies have been conducted using different parts of plantssuch as leaves, seedlings, roots, stems and so on, and their optical properties have been analyzed to study plantphysiology, influence of environmental cues on plant metabolism, light propagation through plant parts and thelike. Thus, it is essential to study in detail the optical properties of several plant parts to determine theirstructural relationship. In this backdrop, an experimental study was conducted to observe and analyze theoptical properties of node and inter-nodal tissue cross-sections of the plant Alternanthera philoxeroides under apolarizing microscope constructed and standardized in the laboratory. The observed optical properties of themicroscopic tissue sections have been then studied to determine a significant structural relationship betweennodal and inter-nodal tissue arrangement patterns as a whole. Tissue sections that have undergone a sort ofbiological perturbation like loss of water (dried in air for 15 min) have also been studied to study the change inthe pattern of tissue optical property when compared with that of normal plant-tissue cross-sections under apolarizing microscope. This type of biological perturbation was chosen for the study because water plays animportant role in maintenance of the normal physiological processes in plants and most other forms of life.
