What is the Role of Nutrition in Plants?

Nutrition in plants is essential for their life and growth. Plants obtain their food from their surroundings. The food consists of certain essential elements that are taken up by the roots and transported to the other parts of the plant for nourishment. These elements can be divided into two categories: macronutrients, which are required in large quantities, and micronutrients, which are required in small amounts. Macronutrients include carbon, oxygen, hydrogen, nitrogen and phosphorus. Micronutrients include calcium, magnesium and sulfur. These vitamins play an important role in proper plant growth as they help with producing enzymes and hormones necessary for plant development.
