Document Summary

Overview: no two plants are alike: the fanwort, an aquatic weed, demonstrates the great developmental plasticity that is characteristic of plants. The fanwort has feathery underwater leaves and large, flat, floating surface leaves. As a result, no two plants are identical. As a result, grasses make excellent ground cover for preventing erosion: sturdy, horizontal, underground stems called rhizomes anchor large monocots such as palms and bamboo, the root system helps anchor a plant. Some arise from roots while adventitious roots arise aboveground from stems or even from leaves: some modified roots provide additional support and anchorage. In some plants, companion cells in leaves help load sugar into the sieve-tube members, which transport the sugars to other parts of the plant. In contrast, most animals and certain plant organs, such as flowers and leaves, undergo determinate growth, ceasing to grow after they reach a certain size.
