inorganic ions

Question 1

what are the two groups of inorganic ions

Answer 1

1. macronutrients
2. micronutrients

Question 2

What quantity of macronutrients are needed in living organisms

Answer 2

Small amounts

Question 3

What quantity of micronutrients are needs in living organisms

Answer 3

Very small amounts

Question 4

What can a lack of macro/micro nutrients lead to

Answer 4

Deficiency diseases

i.e. Disease caused by their being not enough inorganic ions

Question 5

Why is the organic compound Calcium (Ca²⁺⁾ important in plants

Answer 5

Calcium pectate is an important component of the middle lamella of plants

A deficiency leads to stunted growth

Question 6

Why is the organic compound Sodium (Na⁺⁾ important

Answer 6

it helps to maintain the electrical and osmotic balance accross the cell membrane

i.e. Vital in active transport

Question 7

Why is the organic compound Chloride (CL^-)important

Answer 7

it helps to maintain the electrical and osmotic balance accross the cell membrane

Needed for carbon dioxide transport in the blood and is a component of stomach acid

Question 8

Why is the organic compound Potassium (K⁺⁾ important

Answer 8

Plays an Important part in cell membrane function

and nerve impulse transmissions and

other active transport mechanisms

Needed for protein synthesis and is an important cofactor in respiration

If deficient in plants leads to yellowing on the leaf edge and dead spots

Question 9

Why is the organic compound Magnesium (Mg²⁺ ) important

Answer 9

Important component of chlorophyll and is what makes leaves green

If deficient leads to Chlorosis (yellow leaves)

Question 10

Why is the organic compound Nitrate (NO^3-) important

Answer 10

important source of nitrogen for a number of biological molecules including

• Amino acids
• Proteins
• Nucleic acids
• Coenzymes
• ATP
• Hormones

Deficiency in plants leads to chlorosis and yellow leaves

Question 11

Why is the organic compound Phosphate (PO₄^3-) important

Answer 11

An important element in the formation of:

• ATP
• Nucleic Acid
• Coenzymes

Has a role in the phopholipid component of cell membranes

Major structural role in bones and teeth

Deficiency in plants resulting in poor root growht and purple younger leaves.

Question 12

Why is the organic compound Calcium (Ca²⁺⁾ important in animals

Answer 12

Important component of bones and teeth

and…. is involved in the process of muscle contraction and blood clotting

A deficiency leads to rickets and blood clotting disorders
