items.

6. A source of vitamins: 

Plants are the largest source of essential vitamins
to the body. The body cannot manufacture
vitamins on its own for metabolism.


7. Natural fertilizes and pesticides:
Plants are also the source of fertilizes and pesticides. Using
artificial pesticides are harmful to the environment. They may
even enter food causing health issue to human and animals.

Using these naturally derived pesticides are safe. They
degrade with time and even do not harm the soil.


8. Biofuels:
Some plants are also grown for the sake of biofuels. The plant’s fuel is less toxic since it does
not emit harmful gasses and also less expensive.


9. Economic contribution:
Plants are great contributors to an economy. Many countries rely on agriculture as one of the main sources of
revenue.
Plants are responsible for the production of food, cosmetics, drugs, cloth, honey, gum, tannins, essential oils
(perfumes), alkaloids, resins, etc. which are all money yielding.
So plants provide a great contribution to economic growth. Even now many countries economies are primarily
dependent on plant products.
