One could and indeed did for quite a long time quite usefully study morphology without ever knowing anything about cells. Complex structures are possible without cellular arrangement Figs. Of course, the rarity of true large cellular plants and the enormous diversity of multicellular plants show that multicellularity is a more favorable basis for the evolution of large organisms than the enlargement and increased complexity of single cells. Prerequisites for the formation of multicellular organisms include not only the massing together agglomeration of cells but also the ordered differentiation of initially identical cells. The signals for the appropriate local differentiation must be conveyed by every cell in a meristem.

This contribution represents an extension of an earlier report covering the morphology and anatomy of the stem of flowering plants Dickison As such, I have found it convenient to organize recent research under many of the same topic headings that were recognized previously. This chapter is different from my first contribution, in that selected literature devoted to root organization and structure is also summarized briefly. As before, this is not intended as an exhaustive literature review but a selection of current research that represents an overview on the progress made in the field of stem and root morphology and anatomy during the past few years.
Plant morphology or phytomorphology is the study of the physical form and external structure of plants. Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarity of plan and origin". First of all, morphology is comparative , meaning that the morphologist examines structures in many different plants of the same or different species, then draws comparisons and formulates ideas about similarities.
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. Originally it included plant morphology , the description of the physical form and external structure of plants, but since the midth century plant anatomy has been considered a separate field referring only to internal plant structure. Some studies of plant anatomy use a systems approach, organized on the basis of the plant's activities, such as nutrient transport, flowering, pollination, embryogenesis or seed development. He developed concepts of plant morphology and classification, which did not withstand the scientific scrutiny of the Renaissance. A Swiss physician and botanist, Gaspard Bauhin , introduced binomial nomenclature into plant taxonomy. He published Pinax theatri botanici in , which was the first to use this convention for naming of species. His criteria for classification included natural relationships, or 'affinities', which in many cases were structural.
