Anatomy, a field in the biological sciences concerned with the identification and description of the body structures of living things. Plant anatomy is the study of the shape, structure, and size of plants. As a part of botany, plant anatomy focuses on the structural or body parts and systems that make up a plant. A typical plant body consists of three major vegetative organs: the root, the stem, and the leaf, as well as a set of reproductive parts that include flowers, fruits, and seeds. Let's know more about Anatomy of Flowering Plants.
