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.
Meteor: If a meteoroid enters the Earthâs atmosphere and vaporizes, it becomes a meteor, which is often called a shooting star. Meteorite: If a small asteroid or large meteoroid survives its fiery passage through the Earthâs atmosphere and lands on Earthâs surface, it is then called a meteorite.Another related term is bolide, which is a very bright meteor that often explodes in the atmosphere. This can also be called a fireball.n short, the difference between asteroids and meteors all comes down to a question of location. Asteroids are always found in space. Once it enters an atmosphere, it becomes a meteor, and then a meteorite after it hits the ground.
