Functions of Carbon, Hydrogen & Oxygen

• Carbon, Hydrogen and Oxygen form about 95% of the dry weight of plants and are obtained from CO2 and H2O. They are converted in to simple carbohydrates by photosynthesis and ultimately elaborated into complex amino acids, proteins and protoplasm. These are the major components of carbohydrates, proteins and fats.

  Functions:

  1. They play a dominant role in the process of photosynthesis and respiration in plants.,
  2. They are involved in the formation of simple as well as complex organic compounds like carbohydrates, starch proteins etc.
  3. Maintaining the structure of the plant cells.
  4. They provide ‘energy’ required for the growth and development of plant by oxidative break down of carbohydrates, proteins and fats during their cellular respiration
