ROCKY PLANETS (Mercury-Venus-Earth-Mars-Pluto). The rocky planets are mostly made up of rock and metal. These planets are very heavy and move slowly. They also do not have rings and very few moons.GAS PLANETS (Jupiter-Saturn-Uranus-Neptune).

Importance of Phosphorus to Plants. Phosphorus is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. Phosphorus is, therefore, important in cell division and development of new tissue. Phosphorus is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield. The phosphorus cycle Topics and concepts Articles and activities Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO 4 3-), located in water, soil and sediments.
