Can any one explain me abt morphology of plants?
Flowers represent the reproductive organ of flowering plants, and are very important in identification because they typically provide characters that are consistently expressed within a taxon (either at the family, genus, or species level). This is because floral characters are under strong genetic control and generally are not affected by changing environments. Certain floral characters may remain the same throughout a family or genus, while other characters are more variable and are used only to differentiate species. For example, floral symmetry, ovary position, type of placentation, and kind of fruit, usually are used to differentiate families or genera, while petal color or shape and size of floral parts are more commonly used to distinguish species. Flowers arise from the apical portion of a stem in a region called the receptacle. They may be borne directly on a main stem axis or rachis (sessile) or on a slender stalk or stem called a pedicel. They usually consist of four whorls
