Abstract: The present work concerns a self-ecological study of Lavatera maritima (malvaceae) in the region of Marsa benmehidi, for this study we are based on histological criteria. Plant organisms and especially flowering plants are distinguished from most animal organisms by remarkable characters. These plants are practically immobile and fixed in the soil. As a result, they depend on the environment around them. This study aims to explore the structure of living organisms, the constitutive and functional relationships between their elements, as well as the renewal of tissues. It allowed us to know the tissues, organs following the leaf, the stem, the root and the different tissues such as xylem, phloem... etc.Abstract: The present work concerns a self-ecological study of Lavatera maritima (malvaceae) in the region of Marsa benmehidi, for this study we are based on histological criteria.
