Plant anatomy focuses on the internal structure of plants.
We explore the different kinds of cells and tissues that make up the plant body. The evolution of plant structure in relation to the transport of water and carbohydrates within the phloem is a theme of interest in Botany. The study of a plant's internal structure reveals much about the relationship between cell types, the arrangement of the cells to form tissues and how these tissues form organs of the plant. Here are some examples that show how Anatomy gives insight into plant structure and function. In Lycopodium claviatum , the central xylem core is very prominent, and looks like a series of finger-like projections.
