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 a vital component of DNA, the genetic memory unit of all living things. It is also a component of RNA, the compound that reads the DNA genetic code to build proteins and other compounds essential for plant structure, seed yield and genetic transfer.he structures of both DNA and RNA are linked together by phosphorus bonds. Phosphorus is a vital component of ATP, the energy unit of plants. ATP forms during photosynthesis, has phosphorus in its structure, and processes from the beginning of seedling growth through to the formation of grain and maturity.
