Introduction:-
The basic needs of all living organisms are essentially the same.They require macromolecules , such as carbohydrates , proteins and fats , and water and minerals for their growth and development. Most of the minerals present in soil can enter plants through roots . The technique of growing plants in a nutrient solution is known as hydroponics.
