Plant Minerals and their Roles in Plant Growth Flashcards
Carbon
Constituent of carbohydrates; necessary for photosynthesis
Hydrogen
Maintains osmotic balance; important in numerous biochemical reactions; necessary in photosynthesis
Oxygen
Constituent of carbohydrates; necessary for respiration
Nitrogen
Constituent of proteins, clorophyll and nucleic acids
Phosphorus
Constituent of many proteins, coenzymes, nucleic acids and metabolic substrates; important in energy
Potassium
Involved in photosynthesis; carbohydrate translocation, protein synthesis, etc.
Calcium
Component of cell wall; plays a role in the structure and permeability of membranes
Magnesium
Enzyme activator; component of clorophyll
Sulfur
Component of plant proteins
Iron
Involved in chlorophyll synthesis and enzyme for electron transfer
Manganese
Controls several oxidation-reduction systems and photosynthesis
Boron
Important in sugar translocation and carbohydrate metabolism
Zinc
Involved with enzyme systems that regulate various metabolic activities
Copper
Catalyst for respiration; component of various enzymes
Chlorine
Involved in oxygen production in photosynthesis
Molybdenum
Involved with nitrogen fixation and transforming nitrate into ammonium
Nickel
Necessary for proper functioning of the enzyme, urease; necessary in seed germination

The following are the conditions required for nutrient uptake by plants:
- Actively growing plants – anything that affects the metabolism of the plant will affect nutrient uptake.
- Metabolic energy – plant roots must be able to respire and soils must have oxygen.
- Root hairs – these are the most active points of nutrient uptake.
Carbon enters almost completely through _______ as CO2 with release of O2 produced during photosynthesis.
