The chemical composition in cells are vital to the survival of the cells.
Deficiency in any one of it will affect the function of the cells.

Chemical Component Consequences of Deficiency
Carbohydrates- Respiration cannot occur. ( No Glucose )- No Storage of food in starch or glycogen form.- Plant cells irregular in shape. ( No Cellulose )
Proteins- Plasma membrane not properly formed.- No carrier and pore protein to transport substance
across the plasma membrane.- No new cells and tissue are formed. ( Inhibit body
growth )
Lipids- No cholesterol to stabilise the plasma membrane.- Biochemical reaction will proceed to slowly to
sustain life.
Enzymes - No chemical reactions in the cells.- All living processes stop functioning.
Nucleic Acids - No DNA and RNA in the cells.- Synthesis of proteins stop.
Water - No chemical reactions occur.- Cells die.
