Question 1

cations

Answer 1

positive ion

Question 2

anions

Answer 2

negative ions

Question 3

macronutrient

Answer 3

needed by an organism in a larger quantity than a micronutrient

Question 4

calcium ions

Answer 4

helps harden body parts such as teeth, bones and exoskeletons
helps with the movement of organisms by regulating the transmission of impulses from neurone to neurone
stimulates muscle contraction
helps regulate protein channels, which affects the permeability of cell membranes
necessary for the formation of blood clots#

Question 5

sodium ions

Answer 5

regulate osmotic pressure (help plant cells remain turgid)
regulate the absorption of water in the kidney
help transmit nerve impulses
maintain ph of body
used in active transport

Question 6

potassium ions

Answer 6

nervous transitions
osmotic potential
assists active transport 
maintains PH
helps grow healthy leaves and flowers
helps synthesis of proteins and glycogen and the breakdown of glucose

Question 7

hydrogen ions

Answer 7

drive production of ATP
determine the PH of fluids
cytoplasmic pH affects the function of enzymes

Question 8

ammonium

Answer 8

source of nitrogen atoms :
organic bases (contain N)
vitamins (contain N)
ammonium ions are formed fro ammonia by accepting a hydrogen ion so they help maintain pH levels

Question 9

nitrate ions

Answer 9

source of nitrogen
nitrogen: amino acids which make up proteins
organic bases
vitamins
chlorophyll

Question 10

hydrogen carbonate ions

Answer 10

formed when CO2 dissolves in blood
transport of CO2 in the blood
regulate blood pH

Question 11

phosphate ions

Answer 11

component of many biological molecules e.g. nucleotides
ATP
phospholipids
breakdown of glucose in respiration
