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.
In fertilizer, phosphorus comes in the form of phosphate, which dissolves over time to strengthen the root system and encourage longer plant growth. Some of the functions of phosphorus are to: 1  Stimulate growth. 2  Phosphorus gives plants a strong starting point in developing a root filter system in the soil.or example, if the fertilizer analysis is 12-2-14, the fertilizer contains 2% phosphorus. The other numbers indicate nitrogen and potassium, respectively. It should be noted that some municipalities ban the use of phosphorus on lawns.
