APES, Period 3
Terms
• Sedimentary Cycle
• Multivalent
• Allotropic
• Phosphate
• Organophosphate
Term 1
Sedimentary Cycle
-Elements moving from land to water to sediment (solid fragments of material that come from the weathering of rock and are carried and deposited by natural methods)
-The Sedimentary Cycle is known as
the Phosphorus Cycle.
Term 2
Multivalent/Polyvalent
-Having a valence of 3 or higher.
-found in nature in several allotropic forms
Term 3
Allotropic
-The existence of two or more
crystalline or molecular structural forms
of an element.
-It is found in nature in
several allotropic forms
Term 4
Phosphate -The existence, especially in the solid
state, of two or more crystalline or molecular structural forms of an
element. -Phosphorus is commonly found in the
environment as phosphates
Term 5
Organophosphate
-the general name for esters of phosphoric acid.
Ecological Importance
• Concentrated phosphoric acids are used in fertilizers for agriculture and farm production.
• Plant growth and development requires phosphorus
• Phosphorus is essential for early root development and hastens plant maturity.
• Phosphorus, mainly in the form of the ions, is an essential and important nutrient of both animals and plants.
Location• Present throughout the
universe
• Part of the atmosphere and the sun
• In meteorites
• Molten material
• Usually found in combination with oxygen
Biological Importance
• Phosphorus is a mineral that makes up 1% of a person's total body weight.
• Plants and animals- phosphorus is found in complex organic compounds in the blood, muscles, and nerves (ex: adenosine triphosphate: ATP, calcium phosphate)
• The main function of phosphorus is in the formation of bones and teeth
• It is important in utilizing the body's carbohydrates and fats.
• Phosphorus compounds are essential in the diet; they are added to foods and animal feeds (ex: Organic phosphates, ferric phosphate, tricalcium phosphate, and dicalcium phosphate)
Phosphate in the atmosphere
• None are found in the gaseous state
• Usually in liquid form
• Dust particles
Phosphate in the lithosphere
• Phosphorus is found in sedimentary rocks and soil
• Main mineral found in phosphate containing rocks is called apatite
• Phosphorus found in insecticides, fireworks, detergents, fertilizers, and matches
Phosphorus in the Hydrosphere
• Used by all marine creatures
• Circulated through the food chain or deep in the ocean floor
• Some phosphate deposited in the shallows
Phosphorus in the Biosphere
• Phosphorus is present in almost every living organism in the biosphere
• Essential nutrient for animals and plants
