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.
1 Phosphorus-this nutrient is critical in the germination and growth of seeds, flowers, fruit, and roots. 2  When phosphorus is deficient, growth is reduced and leaves fall off prematurely. 3  Plants lacking phosphorus produce dull, bluish-green leaves that turn a purplish or bronze color with brown edges.ater and air provide plants with three necessary nutrients: carbon, hydrogen and oxygen, however, in the soil there are thirteen more nutrients needed for plants to grow. This is why a soil test can help you grow healthy, verdant plants.
