Among all the vegetative organs of the plant, the leaf is considered to have the highest morphological and anatomical plasticity; the influence of environmental factors on the anatomical structure of the leaf is much more obvious and relevant than in the case of the other vegetative organs of the plant (root, stem), mainly due to the multiple functions played by the leaf, leaf metamorphoses, the position of the leaf in relation to the stem, and the living environment (Bannister 1976; Grigore 2022).
