This plant biology course helps students understand the structure, function, and diversity of plants, from the cell to the entire organism, by successively covering the plant cell, tissues, the anatomy and morphology of organs (root, stem, leaf, flower), basic physiology (photosynthesis, nutrition, growth), and plant reproduction (asexual and sexual). It uses clear diagrams, practical exercises, and concrete examples to prepare students for tests and exams, whether at the high school level (Life and Earth Sciences) or in the first, second, and third years of biology/agronomy, master's programs, engineering programs, etc.
