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 in soil organic matter accounts for about 20 to 65% of the total phosphorus found in soils. Therefore, phosphorus mineralization from soil organic matter is an important source of available phosphorus for plant growth. Phosphorous ranks second to nitrogen as a limiting nutrient for plant growth.icronutrients are plant essential elements that are required by plants in much smaller amounts than the other essential nutrients. Generally, less than 1 lb/acre of each micronutrient will be present in the aboveground portion of crops.
