The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.hese two systems are common to nearly all vascular plants, and provide a unifying theme for the study of plant morphology. By contrast, the reproductive structures are varied, and are usually specific to a particular group of plants.
Ash fruits (left: white ash, right: green ash) Click on an image for further information about it. Leaves Ash leaves are pinnately compound. That means that the leaflets are arranged in rows on opposite sides of the central stem (rachis) of the leaf. White and green ash leaves typically have 5 to 9 leaflets, while blue ash typically has 7 to 11 leaflets. There are a number of common tree species that have leaves like this. However, most of them have leaves that are arranged alternately on the twig, whereas ash tree leaves are arranged oppositely on the twig.
