Vegetative and Reproductive Characters
Plant morphology treats both the vegetative structures of plants, as well as the reproductive structures.
The vegetative (somatic) structures of vascular plants include two major organ systems: (1) a shoot system, composed of stems and leaves, and (2) a root system. These 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. Structures such as flowers and fruits are only found in the angiosperms; sori are only found in ferns; and seed cones are only found in conifers and other gymnosperms. Reproductive characters are therefore regarded as more useful for the classification of plants than vegetative characters.

Famous quotes containing the words vegetative, reproductive and/or characters:
“Virtuous people are simply those who have ... not been tempted sufficiently, because they live in a vegetative state, or because their purposes are so concentrated in one direction that they have not had the leisure to glance around them.”
—Isadora Duncan (1878–1927)
“The blind conviction that we have to do something about other people’s reproductive behaviour, and that we may have to do it whether they like it or not, derives from the assumption that the world belongs to us, who have so expertly depleted its resources, rather than to them, who have not.”
—Germaine Greer (b. 1939)
“Of all the characters I have known, perhaps Walden wears best, and best preserves its purity. Many men have been likened to it, but few deserve that honor. Though the woodchoppers have laid bare first this shore and then that, and the Irish have built their sties by it, and the railroad has infringed on its border, and the ice-men have skimmed it once, it is itself unchanged, the same water which my youthful eyes fell on; all the change is in me.”
—Henry David Thoreau (1817–1862)
