A spiral galaxy is a galaxy where the stars and gas clouds are concentrated mainly in one or more spiral arms. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a concentration of stars known as "the bulge". The disk of stars orbiting the bulge separates into arms that circle the galaxy. These spiral arms contain gas and dust and younger stars that shine brightly before they dull. Most of the galaxies that scientists have discovered so far are spiral galaxies. One example of a galaxy in our solar system is The Milky Way. Spiral galaxies make up roughly 72 percent of the galaxies that scientists have observed. How the spiral arms form continues to puzzle scientists. One theory suggests the galaxy arms could be the result of density waves traveling through the outer disk. Galaxies at a whole are quite a fascination.

Answer:Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.
