Histochemical Staining of Plant Tissues

Abstract

Histochemistry is a subfield of histology that focuses on identifying the chemical components of cells and tissues. Starch deposition occurs throughout the plant body, but seeds, the parenchyma of secondary vascular tissues in the stem and root, tubers, rhizomes, and maize are notably affected. The protoplast's main ergastic components are starch and proteins. Tannin, a diverse collection of phenol derivatives that are usually related to glucosides, is prevalent in the leaves (xylem) of many plants. Saponins are a type of saponin that is extremely rare. Fats are broadly dispersed throughout the plant body, and they are likely present in minute quantities in each plant cell. Fats are a common reserve resource in meristematic cells such as seeds, spores, and embryos. The breakdown product of carbohydrates is glucosides. Alkaloids are the byproducts of protein breakdown. Many plants have secondary products that are medicinally valuable. Using stains, markers, and light and electron microscopy, histochemistry studies the identification and distribution of chemical substances within and between biological cells. Histochemistry is a methodological approach that allows the chemical analysis of cells and tissues in relation to their structural organisation , but for plant secretory structures, a broad histochemical analysis is required because the same gland and even the same glandular cell can produce multiple metabolites at the same time.
