The study of the tissue and cell structure of plant organs is known as plant anatomy or phytotomy. When it comes to plants, anatomy refers to features that can be seen under a high-powered light microscope or an electron microscope.
Morphology is the branch of biology concerned with the form of living entities. Plant morphology, also known as phytomorphology, is the study of a plant's physical form and visible structure, whereas plant anatomy is the study of a plant's interior structure, typically at the cellular/microscopic level. A morphologist compares and formulates opinions about similarities in a variety of plants from the same or different species. Plants' vegetative (somatic) and reproductive structures are studied.
