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 responsible for nearly all of the developmental aspects of plant growth. Urea phosphate is created by mixing urea with orthophosphoric acid, and it is the primary contributor of nitrogen to plants. Ammonium phosphate contains micronutrients, such as calcium oxide, magnesium oxide and sulfur. In solid form, ammonium phosphate is 11 percent nitrogen and 48 to 55 percent phosphorus oxide. Zinc sulfate is responsible for regulating carbohydrates and protein in plants. Copper is responsible for metabolizing nitrogen.
