The phosphorus cycle is the biogeochemical cycle that involves the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based materials do not enter the gaseous phase readily, [1] as the main source of gaseous phosphorus ...

Description. Papaveraceae are known for diverse and colorful flowers with distinctive sepals. The plants may be annual, biennial, or perennial. Usually herbaceous, a few species form shrubs or evergreen trees. All parts contain a well-developed system of latex ducts called "laticifers", that produce milky latex, a watery white, yellow or red juice.
In botany, a perennial plant or simply perennial is a plant that lives more than two years. [ 1][failed verification] The term ( per- + -ennial, "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth ...
