Inorganic Ions Flashcards
Definition of Inorganic Ions
Molecule that contains no more than one carbon atom
what are the two groups of inorganic ions?
macronutrients - needed in small concentrations
micronutrients - needed in minute concentrations eg. copper and zinc
name the 4 inorganic ions we must be aware of
magnesium
iron
phosphate
calcium
describe magnesium’s functions in plants and animals
plants: constituent of chlorophyll (photosynthesis)
mammals: important in bones
describe iron’s functions in plants and animals
constituent of haemoglobin which transports oxygen in red blood cells
describe phosphate’s functions in plants and animals
used to make nucleotides, including ATP, DNA, RNA
constituent of phospholipids
describe calcium’s functions in plants and animals
mammals: structural component of bones and teeth
plants: provides strength as a component of plant cell walls
define molecules and give an example
two or more group of atoms bonded together eg. glucose
define ions and give an example
