Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy. Related Images:

Hydrogen (H)
When they photosynthesise, plants use sunlight to break apart water into hydrogen and oxygen, and then combine the resulting hydrogen with carbon dioxide from the air to create carbohydrates. Related Images:
Potassium (K)
A primary plant nutrient, especially important for developing strong roots and stems. In fertilizers, usually expressed as potash. Related Images:
Phosphorus (P)
Phosphorus is a primary plant macronutrient, especially important for flower production. In fertilizer, usually expressed as phosphate. Related Images:

Phosphorus
Phosphorus is a nonmetallic chemical element with symbol P and atomic number 15. A multivalent pnictogen, phosphorus as a mineral is almost always present in its maximally oxidised state, as inorganic phosphate rocks. Elemental phosphorus exists in two major forms Related Images:
Potassium
Potassium is a chemical element with symbol K (derived from Neo-Latin kalium) and atomic number 19. Elemental potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water, generating sufficient heat to ignite the hydrogen emitted in the reaction and burning with a lilac flame. Naturally occurring potassium […]
Calcium
Calcium is the chemical element with symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, and is the fifth-most-abundant element by mass in the Earth’s crust. Calcium is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Calcium is essential for […]
Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. Its common oxidation number is +2. It is an alkaline earth metal and the eighth-most-abundant element in the Earth’s crust and ninth in the known universe as a whole. Magnesium is the fourth-most-common element in the Earth as a whole (behind iron, […]
