Polysaccharides are the most abundant carbohydrates. A polysaccharide molecule can contain thousands of glucose units. These highly complex carbohydrates include starches, cellulose, and glycogen. Starch is the usual form in which carbohydrates are stored as energy by plants.Plants can split starch into its simpler glucose units for use as energy when needed. Cellulose is known as a structural carbohydrate because of the fibers formed by its molecules.tarch is the usual form in which carbohydrates are stored as energy by plants.

When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or shooting star.
Meteoroid-A small particle from an asteroid or comet orbiting the Sun. Meteor-A meteoroid that is observed as it burns up in the Earthâs atmosphere â a shooting star. Meteorite-A meteoroid that survives its passage through the Earthâs atmosphere and impacts the Earthâs surface.In summation, an asteroid is a relatively small object out in space.When an asteroid breaks through our atmosphere and burns up, it becomes a meteor. If the asteroid manages to get all the way through our atmosphere and actually hits the surface of the planet, it is classified as a meteorite.eteor-A meteoroid that is observed as it burns up in the Earthâs atmosphere â a shooting star.
